In C Programming: NOT in JAVA OR C++

CODE the function Sec(x) using Newton Raphson.

Search for, Select, and Define a numerical algorithm

Test the algorithm manually using a spreadsheet or calculator

Write a pseudocode version for the algorithm

Implement the pseudocode as a C function, and a main() function that calls it

Debug the code

Test the algorithm with a minimum of 50 test cases including extremes and invalid inputs.

Note: The algorithm must have the following characteristics:

* Use floating point variables (doubles are preferred over float variables)

* Use iteration to converge on a solution

* Multiple test cases must be used to demonstrate correct operation of the algorithm
