(Continued from above)
Compare sine with inverse sine (General Difference):
Sine is the ratio of two sides of a right triangle (opposite and hypotenuse). Inverse or sin^{1} is an operation
that uses the same two sides of a right triangle as sine does (opposite over hypotenuse)
in order to find the measure of the angle i.e. sin^{1} is the measure of
angle.
Thus the key difference is: although both sine and inverse sine involve the opposite
side and hypotenuse of a right triangle, the result of these two operations are
different. One operation (sine) finds the ratio of these two sides; the other operation,
sine inverse, actually calculates the measure of the angle (using the opposite side
and the hypotenuse.
It will be true in the similar way for cos and cos^{1}. But remember cos is the ratio
of two sides of a right triangle (adjacent and hypotenuse).
The video above will explain more in detail about Inverse Cosine and Sine,
and how to apply the concepts in solving realworld problems. This is explained with the help of several examples and done watching video. This helps you to deal with solving problems and help doing the Geometry home work.
