## Homework Statement

find the partial derivative with respect to x

## Homework Equations

f(x) = (alpha)x^2

alpha is a just to represent units N/m^2

## The Attempt at a Solution

well, i know that during a partial derivative all variable but the one of interest, x in this case, are held constant. so i don't understand why the derivative is not (alpha)2x. it is 0 according to my prof, and i don't understand why.

if it helps this is a conservative test in physics

f = (x^2i + y^2j)alpha

i want to make sure that the derivative of these two components are equal, they obviously cannot be if one is alpha2x and the other is alpha2y
