please help with matlab integral.

using this format:

clear; clc;

f1=@(x) ();

A=; B=;

I = quad(f1,A,B)

I tried myself with this but none of these can't be run. please help

clear; clc;

f1=@(x) (1/(5*exp(3*x)+2*exp(-3*x)));

A=0.0; B=3.0;

I = quad(f1,A,B)

A=0; B=1;

I = quad(inline('log(1+x)./(1-x)'), A, B);

fprintf('I = %10.6f ', I);

A=0; B=1;

I = quad(inline('log(1+x)./(1-x.^2)'), A, B);

fprintf('I = %10.6f ', I);

Use MATLAB's integral function to evaluate the following integrals. Note that integrals d, e and fare improper integrals. 3.x Sin x ax 1-4 sin x c. /-(sinh x- cosr)dr 3 e dx log x dx log x dr
