code for integral function

∫_r^(r+d)▒(E0 〖(Es) 〗^2 d^2 y^2 dy)/((d+r)^2 d^3 )

how to write code for this function in matlab.please help

The common way to do this will be like:

syms r d y;

f= (r^(r+d))*( d^2 * y^2)/( (d+r)^2*d^3 )

F = int(f, y) % Calculate undefinite integral using variable y

G= int(F,x) % and again using x

a=int(F, x, -15, 15) % for definite integration

Good luck :)
