Im stuck ! Thank you

Code Ive done is underneath it will complete A-E. I need F,G , 2 and 3

%Define a symbolic variable %Define a symbolic Function %call trap function program

function I = trap(func, a, b, n, varargin) % program is trap setting the function a = Upper bound, b = lower bound, n = amount of trapezoids % inputs: % func = name of function to be integrated % a, b = integration limits % n = number of segments (default = 100) % outputs: % I = integral estimate if nargina) % states that the upper cant be greater then the lower bound and prints error error ('upper bound must be greater than lower') % prints upper bound must be greater than lower once error is found end if nargin

True_value=double(-1*(int(func,-108,80)));% takes the intragral and finds the real value

for k=1:n True_Error(k,1)=True_value-Estimate(k,1) AbsRelTruePercentError(k,1)=(abs(True_value-Estimate(k,1))/True_value)*100 end

for c=2:n AbsApproxRelPrecentError(c,1)=(abs(Estimate(c,1)-Estimate(c-1,1))/Estimate(c,1))*100 end
