Inverse sine,cos, tan --What they are and how to use them to find the measure of an angle in a right triangle.
Make sure the computed ratio is present on your calculator and hit the sin^-1 key. This “inverse sine” function takes a known ratio and returns the angle that produced that ratio. For example, sin^-1(0.8) = 53.130 degrees. On some calculators, you may have to hit the sin^-1 key...
Let’s understand how to calculate the value of sin 18 degrees here. How to Find Sin 18 Degree Value Let θ = 18°….(i) We can write 90° as: 90° = 36° + 54° 90 = 2 × 18° + 3 × 18° Substituting (i) in the above equation, ...
Trig Functions:When you're working with angles, keep in mind many calculators let you select whether to express the answerin degrees or radians. Then, you need to determine whether you enter the angle (check the units) and then sin, cos, tan, etc., or whether you press the sin, cos,...
