syms c p d cpd u x real
Pi = sym(pi);
phi(cpd) = 1/sqrt(2*Pi) * int(exp(-x^2/2), x, -inf, cpd)
phi(cpd) = 
f = int(exp(-p)*phi(c*p+d), p, u, inf)
f = 
simplify(f)
ans =

Thats great. I tried using Wolfram alpha but couldn't get the result. Then I tried manually to get the solution. Thanks lot. It is perfect
