C++ language

I Exercise 2: Write a program that generates a table showing the angle 0 (in radians), from 0 to 2n in the step of tr/4, and the corresponding values for sin(O) and cos(0). Moreover, prove the identity that sin?(0) + cos(0) =1 for each value of 0. (sample output is in the next page). Hint: Declare and initialize n as const double PI=3.14159; Use a for loop with theta (angle) varying from 0 to 2*T, with end of iteration expression incrementing theta by rt/4. Hint 2: You can specify the format of the output using cout.setprecision(5); and cout
