    Hi there,
    Basically I'm working through an exercise where I need to estimate the value of pi by using series expansion.
    I've just created my function file as follows:


    function [pi_approx_inc] = pi_approx_arg(k)

    pi_approx_inc = 1/16^k((4/8k+1)-(2/8k+4)-(1/8k+5)-(1/8k+5)-(1/8k+6));


    In the editor however, the first line bar function has a red line under it and claims to have never been set?

    Also I get a red line underneath the k in 4/8k+1. Claiming to be of an invalid syntax?


    I'm uncertain what I'm doing wrong here, and would gladly appreciate any feedback.

    Kind regards,
    Matt
