Find the first partial derivative with respect to u
Find the first partial derivative with respect to c
∂u∂p=c1
Simplify
p=cu
Find the first partial derivative by treating the variable c as a constant and differentiating with respect to u
∂u∂p=∂u∂(cu)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂u∂p=c2∂u∂(u)c−u×∂u∂(c)
Use ∂x∂xn=nxn−1 to find derivative
∂u∂p=c21×c−u×∂u∂(c)
Use ∂x∂(c)=0 to find derivative
∂u∂p=c21×c−u×0
Any expression multiplied by 1 remains the same
∂u∂p=c2c−u×0
Any expression multiplied by 0 equals 0
∂u∂p=c2c−0
Removing 0 doesn't change the value,so remove it from the expression
∂u∂p=c2c
