Find the first partial derivative with respect to h
Find the first partial derivative with respect to p
∂h∂λ=p1
Simplify
λ=ph
Find the first partial derivative by treating the variable p as a constant and differentiating with respect to h
∂h∂λ=∂h∂(ph)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂h∂λ=p2∂h∂(h)p−h×∂h∂(p)
Use ∂x∂xn=nxn−1 to find derivative
∂h∂λ=p21×p−h×∂h∂(p)
Use ∂x∂(c)=0 to find derivative
∂h∂λ=p21×p−h×0
Any expression multiplied by 1 remains the same
∂h∂λ=p2p−h×0
Any expression multiplied by 0 equals 0
∂h∂λ=p2p−0
Removing 0 doesn't change the value,so remove it from the expression
∂h∂λ=p2p
