What did you try? – Jonas Teuwen Dec 12 '10 at 22:46
vishal, usually you explain what you tried, where you had problem, etc. You don't simply expect people to solve it for you, especially if this is homework. – Vivi Dec 12 '10 at 22:49
Well this is not homework :) I guess, I am getting confused in understanding how to take a partial derivative wrt to the W and t. I could do the ones without the intergral. – vishal Shekhar Dec 12 '10 at 23:06

$d Z_t = g(t) d W_t$. If you have problems with this, you should redo basics of stochastic calculus and Brownian motion.
