Symbolic plotting of Fourier integral

I want to plot M/P×a v/s (x/a) there are no values PS - The given equation is of bending Moment for an infinite beam

If there are no values, then there is no plot, since plots require numbers.

If you have values, make the appropriate substitutions here:

P = 42;                                         % Create Variable Value
a = 5;                                          % Create Variable Value
M = @(x,P,a) P*a/pi*integral(@(alfa) alfa.*cos(alfa.*x./a) ./ (alfa.^3+1), 0, Inf, 'ArrayValued',1);

x = linspace(0, 100);

figure
plot(x/a, M(x,P,a)./(P*a))
grid

to get the result you want.
