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
