Symbolic integration in Matlab can be done, syms x f = x^2; int (f) For the definite integral, for example from 0 to 1 is den by int (f,0,1) Use this toolbox to find the integrals of S f(x) = xex, F = f(x) dx g(x) = (x+1) sin(x), G(x) = f g(x) dx. Plot the function G(x) and g(x). Script> 1 syms x 2 f = ; 3 F = ; 4 g = ; 5 G = ; 6 fplot( ) 7 figure 8 fplot( )
