What Is Sin -1 - In order to define the inverse functions, we have to restrict the domain of the original functions to an interval where they are invertible. Web we’ll try to untangle the notations of sin−1 and arcsin. Web so what should be sin − 1. Recall that inverse trig functions are the inverses of trigonometric functions such as sine and cosine. For example, since we know that sin(π 6) = 1 2, the inverse function swaps the input and output, so that sin−1(1 2) = π 6. These domains determine the range of the inverse functions. For example, sin30 = 1/2. For more explanation, check this out.
