How do you find a cotangent?
1/(tangent of angle)
What is the cos of angle A?
It is a trigonometric function which converts the angle into a ratio.If the angle A is measured in radians, thencos(A) = 1 - A^2/2! + A^4/4! - a^6/6! + ...
What fraction of a turn is a obtuse angle?
It is a fraction between 1/4 and 1/2.
How do you draw angles greater than 180?
First, if the angle is 360° or more, find the remainder of the angle divided by 360 - this is as 360° represents a full turn. If you have a 360° protractor just measure off the angle. If you only have a 180° protractor, then there are two ways it can be done as the protractor is marked so that 0° - 180° can be measured from either end of the base line: Method 1: excess over 180° 1) Subtract 180° from the angle to get the excess over 180°. 2) Place the protractor on the line, centred on the vertex of the angle on the left of the line, with the top 0°/180° mark on the line. 3) Measure the excess over 180° calculated in step 1 from the bottom 0° mark of the protractor. 4) Draw in the second angle arm - the reflex angle (measured clockwise) is as required. Method 2: acute/obtuse angle of the reflex angle to complete a full turn 1) Subtract the angle from 360° to get the angle which completes the full turn 2)Place the protractor on the line, centred on the angle vertex on the left of the line, with the top 0°/180° mark on the line. 3) Measure the angle to complete the full turn calculated in step 1 from the top 0° mark of the protractor (on the line). 4) Draw in the second angle arm - the reflex angle (measured clockwise) is as required. The above assume a clockwise angle is being drawn from a vertical line with the angle vertex at the bottom. For anticlockwise angles, place the protractor on the right of the line. For a non-vertical line [mentally] rotate the paper so that the first arm of the angle is vertical with the angle vertex at the bottom.
What is a quadrantal angle?
A Quadrantal angle is an angle that is not in Quadrant I. Consider angle 120. You want to find cos(120) . 120 lies in quadrant II. Also, 120=180-60. So, it is enough to find cos(60) and put the proper sign. cos(60)=1/2. Cosine is negative in quadrant II, Therefore, cos(120) = -1/2.
Are hill percentages the same as degrees?
No. A percentage gradient tells you how many you go up or down for every 100 along, for example a gradient of 5% means for every 100m along you go, you will go up or down 5m. Given a percentage gradient, converting it to a decimal (by dividing by 100) will give the TAN of the angle of the slope, for example a gradient of 5% means the angle = arctan(5/100) = arctan(0.05) ~= 2.9o. The 1 in x gradient that tells you for every 1 up or down you go you go x along, for example 1 in 20 means you will go up or down 1 yd for every 20 yds along.
What is the angle between a line of a graph and a positive direction of the x-axis?
The angle is the arc-tan of the gradient of the line. That is to say, the tangent of that angle is the gradient of the line or the angle between the straight line and the positive x-axis. Arc tan may also be written as tan-1 but that is frequently confused with 1/tan or the cotangent function.
In a triangle the second angle is twice the first angle and the third angle is 20 less than the first angle find the measure of all three angles?
Remember the sum of the 3 angles of a triangle = 180degrees Let angle 1 = x angle 2 = 2x angle 3 = x-20 Sum = x + 2x + x - 20 =180o 4x - 20 = 180o 4x = 200o x = 50o 2x = 100 o x - 20 = 30o angle 1 = 50o angle 2 = 100 o angle 3 = 30o
Need head bolts torque settings for pug 306?
if it is an aluminum block stage 1 20 Nm then stage 2 angle tighten a further 240 degrees if it is a cast iron engine block stage 1 20 Nm stage 2 angle tighten a further 120 degrees then stage 2 angle tighten another 120 degrees these settings are for a petrol engine
The gradient of the line y2x 1?
If you mean: y = 2x+1 then the gradient is 2 and the y intercept is 1
The gradient of x y2?
x+y=2 the gradient is -1
What is the central angle of a circle with a diameter of 20 inches and divided into 20 congruent sectors?
1
What is the measure of the angle of elevation of the ramp to the nearest degree of a 20 ft board by 1ft ramp?
sin-1(1/20) = 3 degrees.
What is the gradient of roman aqueducts?
The gradient of the channel of Roman auqducts was 1 in 4800.
How would the slope of a savings graph change if you saved 40 per month instead of 20?
The slope or gradient of a line that represented the change in savings over time would increase (in this case it would double). This is because in the example in your question, you would be saving twice as much money per unit time. As such the gradient of the line would change from 20 (20 / 1) to 40 (40 / 1).
What if The second angle of a triangle is 20 degrees greater than the first angle. The third is twice the second. Find the three angles.?
Angle 1 = 30 degrees Angle 2 = 50 degrees Angle 3 = 100 degrees.
