Inverse radical functions.
sin π cos π = 1/3. We can write this as: sin 2π = 2/3. To solve for π, we must first take the arcsine or inverse sine of both sides. The arcsine function is the inverse of the sine function: 2π = arcsin (2/3) π = (1/2)arcsin (2/3) This is just one practical β¦

For example, if f takes a to b , then the inverse, f β 1 , must take b to a . Or in other words, f ( a) = b f β 1 ( b) = a . In this article we will learn how to find the formula of the inverse function when we have the formula of the original function.When we wanted to compute a heating cost from a day of the year, we created a new function that takes a day as input and yields a cost as output. The process of combining functions so that the output of one function becomes the input of another is known as a composition of functions. The resulting function is known as a composite function. β¦The inverse of a power function of exponent n is a nth root radical function.
