How do calculators calculate Sin Cos and Tan of an angle without side lengths?

The relationship between an angle and the triangle formed by it is always constant. This is also why sin cos and tan obtained from the unit circle can be applied to all triangles with the same angle. All that matters is the ratio of the sides, so the calculator can "pick" any length for one side, and use that and the angle to find the other side(s). This answer will be the same regardless of which triangle you are specifically referring to. Side lengths 3 and 5 will produce the same trig values as sides 21 and 35. Also, given the processing power of most calculators, these values are often programmed in, similar to how many students are "programmed" to know the trig values for major angles such as pi, pi/4, 30deg, and 60deg.

How do you calculate tangent of an angle?
the tangent of an angle is equal to the length of the opposite side from the angle divided by the length of the side adjacent to the angle.
How To Calculate The Size Of An Angle In A Pie Chart?
Calculate the percentage that a particular sector represents of the total value. Then the angle size is 3.6 times the percentage.
What is the ratios function of sin?
The sine of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.In terms of ratios, the sine of an angle is defined, in a right angled triangle, as the ratio of lengths of the opposite side to the hypotenuse.
How do you calculate angles on a hip roof?
use an angle finder
How do you use trigonometry?
Various trigonometric functions, such as sine or cosine, show the relationship between the lengths of sides of a triangle and the angles between those sides. So trigonometry is used to calculate angles, lengths and distances using right triangles. Right triangles are those that have one angle of exactly 90 degrees. Example: You want to find the height of a tree. Measure off a fixed distance from the tree and measure the angle between the ground and the line-of-sight to the top of the tree. The height of the tree = the distance to the tree times the tangent of the angle between the tree and the ground, ie tan(x).
How to calculate the sides of a triangle given the degree of an angle and one side?
The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.
How do you find the measure of an angle to the nearest degree?
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
How to get the area of a right triangle given only 1side?
Not possible without at least one other angle. If you have the length of one side, a ninety degree angle, and one other angle - you can work out the third angle and the lengths of the missing two sides. once you have all three side measurements, it's a simple task to calculate the area.
What is the measure of each interior angle of a irregular hexagon?
This cannot be answered without any given side lengths, since the interior angles of an irregular hexagon are different. Only the angles of a regular hexagon can be found without side lengths, and that is 120 degrees per angle.
What is the csc of a 63 degree angle?
You can calculate this on any scientific calculator. Those calculators don't usually have a special key for the cosecans, but this is the same as 1 / sin(63).
Find the cot of a 68 degree angle?
You can calculate this on any scientific calculator. Those calculators don't usually have a special key for the cotangens, but this is the same as 1 / tan(68).
How do you find an angle of a parallelogram using sides?
You cannot. A parallelogram can be flexed: the angles can be altered without affecting the lengths of the sides.
What are the 3 basic trig ratios and how do they work?
The three basic ratios are sine, cosine and tangent.In a right angled triangle,the sine of an angle is the ratio of the lengths of the side opposite the angle and the hypotenuse;the cosine of an angle is the ratio of the lengths of the side adjacent to the angle and the hypotenuse;the tangent of an angle is the ratio of the lengths of the side opposite the angle and the the side adjacent to the angle.
How do you calculate the missing length of a triangle?
It depends on what other information you have. Knowing the lengths of two sides of a triangle is not enough to calculate the third. You need to have some further information: and angle, the area, the length of an altitude or a median.
How do you find an angle in quadrangle without a protractor?
Measure the two sides adjacent to the angle and the diagonal at the far ends of these sides. Then use the cosine rule to calculate the angle.
What is the area of an irregular triangle shape?
It depends on what information you have. There are formulae for when you have the lengths of all three sides or two sides and the angle between them. If you have only one side and two angles (implicitly all three) you can calculate the lengths of the other sides.
What is a Right and scalene Triangle?
"Right" means that it has a right angle. "Scalene" means that all sides have different lengths."Right" means that it has a right angle. "Scalene" means that all sides have different lengths."Right" means that it has a right angle. "Scalene" means that all sides have different lengths."Right" means that it has a right angle. "Scalene" means that all sides have different lengths.
