valuating your OWN $$Numerical Method$$ in MATLAB Recall Leibniz$$s infinite series exactly represents p as $...$ Let$$s approximate p in MATLAB by summing just the first N max terms of this series, and see how the error changes as we include more terms $($increase the value of N max $).($a$)$ Create a function in MATLAB, saved as piApprox.m$,$ which evaluates the Leibniz series up through N max terms. That is$,$ evaluate the finite series Start the function with the following first line exactly $($so the input is Nmax, output is Approx$)$: function Approx $=$ piApprox$($Nmax$)($b$)$ Create a script in MATLAB, called HW$2\_$pi$.$m$,$ which calls the function above to evaluate Approx for all the following nine values of N max $($each power of $10$ from $1$
