Inverse sine - Inverse cosine - Inverse tangent | Inverse Trig Functions

In this lesson we learn:
- Inverse sine: A function that takes you from side ratios to angles
- Inverse cosine: Another inverse trig function
- Inverse tangent: And one last inverse trig function!

Inverse sine function y = sin−1(x) or sometimes called the arc sine and denoted by y = arcsin(x) whose domain is the interval [−1,1] and whose range is the interval [-Pi/2, Pi/2].
The inverse cosine function y = cos−1(x) or we can called the arc cosine and denoted by y = arccos(x) can be determined in a similar fashion. The function y = cos(x) is one-to-one over the interval [0,Pi].
The inverse tangent function y = tan−1(x) or we can called the arc tangent and denoted by y = arctan(x) can be determined similarly. The function y = tan(x) is one-to-one over the interval (-Pi/2, Pi/2)
