= sin -1 (opposite side to θ/hypotenuse) in the same way, inverse cosine and inverse tan can be determined. fact : if the ratio of opposite side of angle θ and hypotenuse equals to 1, then, θ = sin -1 (1) = sin -1 (sin 90) = 90 degrees the function of ...
For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arcsin button may be labelled asin, or sometimes sin-1.) So the inverse of sin is arcsin etc. When we see ...
The arcsine of x is defined as the inverse sine function of x when -1≤x≤1.When the sine of y is equal to x:sin y = xThen the arcsine of x is equal to the inverse sine function of x, which is equal to y:arcsin x = sin-1 x = y...

Reflect all of y=sin(x) in the line y=x: Throw away all but the correct part of it: Since the range of f(x) = sin(x) is [−1, 1], the domain of the inverse function is [−1, 1]. And since the domain of our function f is [−\pi/2, \pi/2] (since that’s ...

Most maths libraries have a atan2(y,x) function which takes both x and y as operands, which allows it to get round the above problems. In the first quadrant atan2(y,x) is equivalent to atan(y/x) since: tan(a) = sin(a)/cos(a) = opposite/adjacent = y/x ...
