Question

How do you find the partial derivative of the function `f(x,y)=intcos(-7t^2-6t-1)dt`?

Answer 1

You need to be more specific about how `f` depends on `x` and `y`. Are they in the limits of the integral? Are they part of the integrand function? As you wrote it, there's no `x` or `y` dependence on the right-hand side and the derivatives with respect to `x` and `y` would be zero.
