Chapter 4, Problem 4.2P

To determine

To write:

A script “printsindegorrad” that will prompt the user for an angle, prompt the user for (r)adians or (d)egrees, with radians as the default, if the user enters ‘d’, the sind function will be used to get the sine of the angle in degrees; otherwise, the sin function will be used. Which sine function to use will be based solely on whether the user entered a ‘d’ or not (‘d’ means degrees, so sind is used; otherwise, for any other character the default of radians is assumed, so sin is used) print the result.
