there is an introat the end of grade ten but there is a real unit in grade eleven trigonometry is usaully taken during geometry and parts of pre/calculus. Its about 10th and/or 11th grade!
How do you use a theodolite?
Process of Measuring Horizontal Angles Using a Theodolite 1. Setting up the Theodolite: This includes mounting the theodolite on a tripod and making sure it is comfortable for the user. 2. Unlock the upper horizontal clamp. 3. Rotate the theodolite until the arrow in the upper or lower rough sight points to the feature of interest and lock the clamp. 4. Look through the main eyepiece and use the upper horizontal adjuster to align the vertical lines on the feature of interest. 5. The reading is taken by looking through the small eyepiece. Using the minutes and seconds adjuster set the one of the degrees on the horizontal scale so the single vertical line on the bottom scale is between the double vertical lines under the selected degree. 6. The reading is the degree which has been aligned and the minutes and seconds read from the right hand scale and is the horizontal angle from the reference line. Process of Measuring Vertical Angles Using a Theodolite Process of Measuring Vertical Angles 1. Setting up the Theodolite: This includes mounting the theodolite on a tripod and making sure it is comfortable for the user. 2. Unlock the vertical clamp and tilt the eyepiece until the point of interest is aligned on the horizontal lines. Lock the clamp in place. 3. Looking through the small eyepiece, use the minutes and seconds adjuster to align one of the degrees on the vertical scale with the double lines just below it. 4. The reading is the degree that has been aligned and the minutes and seconds is read from the right hand scale. 5. To complete the reading, it may be necessary to measure the distance from the theodolite to the point of interest. The above is al true, but doesn't discuss the practical uses of a theodolite. For example, if you want to know the height of the top of the gable on a house, you could use a theodolite. First, set up the theodolite (btw, I made one with a piece of copper tube, a protractor and a cheap wooden tripod) as noted above, make sure the ground is pretty level between the house and the theodolite, and then measure the distance from the vertical side of the house to the theodolite. (You may choose to move the theodolite so that the distance is the square of a whole number.) Then aim the scope (tube) at the upper-most point of the gable and note the degree of angle on the protractor. If you have pretty level ground between the theodolite and the house, the angle at the intersection of the side of the house and the ground should be 90 degrees. So, now we have two angles (the 90 degrees at the intersection of the side of the house and the ground, and whatever angle you recorded at the theodolite) and a side (the distance from the house to the theodolite). With this information, you can calculate the third angle and the other two sides, one of which will be the hypotenuse and the other will be -- tada! -- the final leg, which will tell you the height of the point you picked out at the top of the gable.
What is the difference between bisection and false position method?
In bisection method an average of two independent variables is taken as next approximation to the solution while in false position method a line that passes through two points obtained by pair of dependent and independent variables is found and where it intersects abissica is takent as next approximation..
What are the differences between a trap and an interrupt?
Trap is actually a software generated interrupt caused either by an error (for example division by zero, invalid memory access etc.), or by an specific request by an operating system service generated by a user program. Trap is sometimes called Exception. The hardware or software can generate these interrupts. When the interrupt or trap occurs, the hardware therefore, transfer control to the operating system which first preserves the current state of the system by saving the current CPU registers contents and program counter's value. after this, the focus shifts to the determination of which type of interrupt has occured. For each type of interrupt, separate segmants of code in the operating system determine what action should be taken and thus the system keeps on functioning by executing coputational instruction, I/O instruction, torage instruction etc.
What does F-0-F-5 when a tornado is rated?
The Fujita Scale rates tornadoes from F0 to F5 based on the severity of the damage they do.F0 is the weakest but most common category. F0 damage includes missing shingles, broken tree limbs, trees with shallow roots uprooted, gutters taken down and some trailers overturned. About 55% of tornadoes are rated F0F1, the next lowest category, is also the second most common. F1 damage includes severely stripped house roofs, severely damaged or mostly destroyed trailers, collapse porches and roofs, and broken windows. About 25% of tornadoes are rated F1F2 is the beginning of what care called significant tornadoes. F2 damage includes roofs torn from frame houses, trailers completely demolished, and cars lifted. large amounts of debris may start to fly. About 15% of all tornadoes are rated F2.F3 is the third strongest and third least common category of tornado. F3 damage includes many or most of the walls in a well-built home collapsed, sometimes with just a few left standing. Most trees will be uprooted. About 4% of tornadoes are rated F3.F4 is the beginning of what are called violent tornadoes. F4 damage consisted of well-built houses completely leveled and left as piles of rubble and trees stripped of their bark. About 1% of tornadoes are rated F4.F5 is the strongest and rarest category on the Fujita scale classified as incredible. F5 damage consists of well-built houses being swept clean off their foundations. Sometimes houses may be carried or thrown large distances. Pavement may be peeled from roads. Less than 0.1% of tornadoes are rated F5.
Why is 90 degree not taken as the angle of reference in trigonometry?
The angle of reference is in the first quadrant, and 90 degrees angle is not in the quadrant.
Why is ninety degree not taken as the angle of reference?
in trig a reference angle is ised to create a reference triangle in the first quadrant by using any point except the origin that lies on the terminal side of the ref. angle and drawing a perpendicular to the x-axis. for 90 degrees the terminal side is the y-axis and the perpendicular would not create a triangle, but just retrace the y-axis.
Why is 90 degrees not taken as the angle of reference?
If I understand the question correctly, the answer is that it is simply a case of convention. For bearings, for example, the reference line is North and angles are measured clockwise. In 2-D polar coordinates, the reference line is the horizontal (going East) and angles are measured in the anti-clockwise direction.
How do you figure out the angles of a circle when one angle is given?
A complete circle is 360 degrees. If one angle is given, then that angle can be taken away. For instance: an angle of 90 degrees is a quarter of a circle - measured clockwise from 0. 90 degrees from 360 means that 3/4 or 270 degrees is remaining.
Why is degrees not taken as the angle of reference in trignometry?
They often are. Sometimes, however, radians are used for the measures of angles and for labeling graphs. This is because later aspects of trigonometry, like polar coordinates, arc lengths, and wave graphs, are more easily explored with radians. Pi commonly appears and is more easily understood as π than as 3.14159.... Circles, with areas of πr^2, are frequent and periods of wave function are almost always expressed in radians. Radians become as useful and widespread as degrees.
What is after trigonometry?
Generally pre-calculus is taken after trigonometry, unless the trigonometry course was supplemented by a pre-calculus course, in which case the next course would be calculus.
What is the measure of the largest angle in an obtuse triangle?
178 degrees is the largest angle for an obtuse angle because 180 is a straight angle and 90 degrees is an right angle and below 90 degrees is an acute angle. Some supposedly say that the answer is 179,But it's not! the reason behind this is because in a triangle all the angles have to add up to 180 degrees. There are 3 points to a triangle so there has to be 2 extra degrees taken off of 180, which equals to 178. Explanation is terms: angle A + angle B + angle C = 180 degrees [Sum of supplementary angles of a triangle] 178 degrees + 1 degree + 1 degree = 180 degrees which makes sense. I figured this out when i was doing homework... Hope this helps you other people
What is the height of a tree when its angles of elevation are 32 degrees and then 45 degrees taken at 8 meters apart?
Using trigonometry the height of the tree works out as 15.15 meters rounded to two decimal places
Is trigonometry before pre-calculus?
They can be taken at the same time.
Does an angle of 95 degrees have a compliment?
Technically, no, because a compliment is the difference between any one angle and 90 degrees. In essence, two compliments make a right angle. If this was taken to this example, you could say, theoretically, that the compliment could be -5 degrees, but I'm not sure about negative angles. If it were a question on a test, if anything, I would put -5
What is the distance and direction of an objects change in position from a reference point?
Distance is the magnitude of the change in position, while direction indicates the path taken relative to the reference point. This information can be used to describe the displacement of an object in terms of distance and angle from the reference point.
What is an angle that totals 90 degrees?
Describing anything as a total means that some process of addition or subtraction has taken place, therefore an angle, meaning a single angle, is not a total of anything. You would have to have at least two angles to form a total. In the case of a 90 degree total, you might obtain that from two angles both of 45 degrees. Or 30 degrees and 60 degrees. Or infinitely many other possibilities.
