which...?

I'm going to take a guess that you've been asked to write a function that implements the secant method for finding roots. So what have you done so far (ie please post your code, as appropriate), and what MATLAB-specific issues are you having?

I'm not able to see the entire question. I see: "Write a Matlab function secant:m which". To be exact: This is not even a question at all.

Hey guys r u able to see the entire question? It's not the secant=cos^-1

It's the secant function which is a complicated equation....

Homework is for YOU to do, for YOU to learn from. We already know how to do it. (And it is not THAT complex of a problem.) So sit down, and make an effort.
