It may have originated as ratios in a right-triangle, but more useful when generalised to all angles. Just a typo. Add a comment. Active Oldest Votes.

Let's apply this to an arbitrary right triangle. When we select the right angle as our angle for the sine function something odd happens. It turns out that the opposite side, in this case, is the hypotenuse!

Angles in Degrees. Not defined. Find the value of. As we know,. Now substituting the values Sin inverse is denoted as Sin -1 and it can also be written as arcsin or asine. Hipparchus is known as the Father of Trigonometry. He also discovered the values of arc and chord for a series of angles.
