# Thread: Expansion of integrals using laplace method

1. ## Expansion of integrals using laplace method

Hi all, I want to find the leading behaviour of
integral 0 to pi/2 √sint e^(−x(sint)^4) dt as x → +∞;
Tried by substituting sint = t but getting stuck. Plz help.

Hey user28691.

What do you mean by leading behavior exactly?
