Now we can translate this into arcsin 4x = 1. Lets assume 4x = y and we get arcsin y = 1. The result is y = P + 2P K. Because y = 4x, so we divide y by 4 and P /2 + 2P K by 4, and we get P /8 + P K/2 for x.
There are many uses of trigonometry. The most common use is to calculate linear velocity. The equation for linear velocity is V = Wr, where V is the linear velocity, W is the angular velocity in radian which is acquire by multiply the speed by 2P , and r is radius of the thing that is rotating. Following is a sample problem:
What is the linear velocity of a wheel if it rotates 45 times a minute, and its radius is 1 ft?
V = Wr
V = 45 x 2P x 1
V = 90P Rotation Feet per Minute.
