∂S∂K=40,4N2
Evaluate
K=40.4SN×N
Simplify
K=40.4SN2
Evaluate
K=40,4SN×N
Multiply the terms
K=40,4SN2
Find the first partial derivative by treating the variable N as a constant and differentiating with respect to S
∂S∂K=∂S∂(40,4SN2)
Use differentiation rule ∂x∂(cf(x))=c×∂x∂(f(x))
∂S∂K=40,4N2×∂S∂(S)
Use ∂x∂xn=nxn−1 to find derivative
∂S∂K=40,4N2×1
Solution
∂S∂K=40,4N2
