Question

I have the question and the answer for this problem I just want to understand the concepts and logic of how to do it step by step

 

LUsing Taylor's thearem, we can obtain a formula to calculate he sine of S sin(x) - x - + (-1) (2n - 1)! Write a function detinition to calculate the sine of x using the formula above. Your function should teminate when the absolute value of the last term calculated is less than 1.0 x 10. You may not use any functions supplied in the cmath.h header file (ie. you cannor use the powx.y) function Your sine function may call other functions, and in this case, you must also wrie the definitions of those functions. You do nor need to comment anything, although, a well-placed comment may provide clarity for the grader. Bonus (2 pes): Briefly explain why the sine function above will always converge. You will only get the bonus points if the sine function is wrimen.
