Sin Cos Functions Implementation in C program
Question :Write functions to calculate the sine and cosine of their input. Choose appropriate types for both argument and return value. The series (given below) can be used to approximate the answer. The function should return when the value of the final term is less than 0.000001 of the current value of the function.
sin x = x - pow(x,3)/fact(3) + pow(x,5)/fact(5)... cos x = 1 - pow(x,2)/fact(2) + pow(x,4)/fact(4)...Note the fact that the sign in front of each term alternates (
--+--+--+...). pow(x,n) returns x to the nth power, fact(n) factorial of n (1 × 2 × 3 × ⋯ × n). You will have to write such functions. Check the results against published tables.(http://publications.gbdirect.co.uk/c_book/chapter4/exercises.html)
