Hey everyone, I'm having some trouble in my Multivariable Calculus class. I hope someone can help! I'm sorry that I don't know how to properly make the integral look pretty! Thanks in advance.

$\displaystyle Integral(Integral(sin(x^2))dx)dy$

the limits are y < x < 3, 0 < y < 3.

Wolfram gives me an answer of 0.955565, but I'd love to know how it came up with this.
