If sin x = 0.8 then the value of x that gives this sine is the inverse and so x = sin−1 0.8, i.e. x = 53°. Figure 1.53 shows the graphs for sin x and its inverse function. In a similar way we can define inverses for cosines and tangents. Sign in to download full-size...
A function is a block of code that performs some operation. A function can optionally define input parameters that enable callers to pass arguments into the function. A function can optionally return a value as output. Functions are useful for encapsulating common operations in a single reusable ...
