Find the first partial derivative with respect to v
Find the first partial derivative with respect to n
∂v∂w=n1
Simplify
w=nv
Find the first partial derivative by treating the variable n as a constant and differentiating with respect to v
∂v∂w=∂v∂(nv)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂v∂w=n2∂v∂(v)n−v×∂v∂(n)
Use ∂x∂xn=nxn−1 to find derivative
∂v∂w=n21×n−v×∂v∂(n)
Use ∂x∂(c)=0 to find derivative
∂v∂w=n21×n−v×0
Any expression multiplied by 1 remains the same
∂v∂w=n2n−v×0
Any expression multiplied by 0 equals 0
∂v∂w=n2n−0
Removing 0 doesn't change the value,so remove it from the expression
∂v∂w=n2n
