The idea is the same in trigonometry. Inverse trig functions do the opposite of the âregularâ trig functions. Inverse sine (sinâ1)(\sin^{-1})(sinââ1ââ)left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the sine.
The inverse cosine function - arccos. For every trigonometry function such as cos, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of cos is arccos etc. When we see arccos A, we interpret it as the angle whose cosine is A.
