I am unsure where to begin with finding this partial derivative.

f(x,y)=integral from y to x of cos(t^2)dt

Using the Fundamental Theorem of Calculus and noting that y is treated as a constant when you differentiate with respect to x:

.

Now note that and use the Fundamental Theorem of Calculus again (note that x is treated as a constant when you differentiate with respect to y):
