must be well documented with comments explaining all steps. 1. Write a function that computes the value of the mathematical constant. The value of it can be approximately computed using the infinite series t = 4(1 - 1/3 + 1/5 - 1/7 + 19. 1 + 1/13 - 1/15 +.....) The function prototype is double compute pi (int n). The function computes the value of using the first n terms of the infinite series and returns the value in odli Double en -9 1. Write a function that computes the value of the mathematical constant n. The value of it can be approximately computed using the infinite series a = 4(1 - 1/3 + 1/5 - 1/7 + 1/9 - 1711 + 1713 - 1/15 + .....) The function prototype is double compute pi (int n. The function computes the value of using the first n terms of the infinite series and returns the value
