arccos ( x) , or cos − 1 ( x) , is the inverse of cos ( x) . arctan ( x) , or tan − 1 ( x) , is the inverse of tan ( x) . Range of the inverse trig functions The trigonometric functions aren't really invertible, because they have multiple inputs that have the same output. For example, sin ( 0) = sin ( π) = 0 . So what should be sin − 1 ( 0) ?$$\sin^2 \theta = 1 - x^2$$ So we know either $\sin \theta$ is then either the positive or negative square root of the right side of the above equation. Since $\theta$ must be in the range of $\arccos x$ (i.e., $[0,\pi]$), we know $\sin \theta$ must be positive. Thus, $$\sin \theta = \sqrt{1-x^2}$$To find the domain and range of inverse trigonometric functions, switch the domain and range of the original functions.
