Hi,
I find my professor doing this a lot of times, here is it:
∫{ ∂(f[x])/∂x } dx = ∫d(f[x])
How is that possible?

Thanks,The partial derivative of a function of several variables treats the other variables as constants so
[tex]\int \frac{\partial f(x,y,z,...)}{\partial x}dx= \int df(x,y,z,...)[/tex]
follows from
[tex]\int \frac{df}{dx}dx= \int df[/tex]
for functions of a single variable.
