When finding fx, variables other than x are treated as constants.
For take the derivative of treating non-x variables as constants.
Find the first and second order partial derivatives for the following function:
f(x,y) = 2x^3 - 6xy^2 +5y^4
Need to find:
I don't understand the concept of finding partial derivatives and my calculus text has (once again) proven itself to be worthless.
Thanks in advance...
