May I get help to

write the code to find sind and cos of angle using functions with "function pass by reference only" and find Sind 2x and Cos 2x using the function for Cos and Sin. only part a

Write a C++ program that calculates the value of the series sin z and cos r, sin 2r or cos 2r where the user enters the value of r (in degrees) and n the number of terms in the series. For example, if n 5, the prograrm should calculate the sum of 5 terms in the series for a given values of r. The program should use switch statements to determine the choice sin r and cos a, sin 2r or cos 2t. (Note: you may have to convert 7 Points degrees to radians for sin and cos functions). b.
