Find the first partial derivative with respect to m
∂d∂v=m1
Simplify
v=md
Find the first partial derivative by treating the variable m as a constant and differentiating with respect to d
∂d∂v=∂d∂(md)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂d∂v=m2∂d∂(d)m−d×∂d∂(m)
Use ∂x∂xn=nxn−1 to find derivative
∂d∂v=m21×m−d×∂d∂(m)
Use ∂x∂(c)=0 to find derivative
∂d∂v=m21×m−d×0
Any expression multiplied by 1 remains the same
∂d∂v=m2m−d×0
Any expression multiplied by 0 equals 0
∂d∂v=m2m−0
Removing 0 doesn't change the value,so remove it from the expression
∂d∂v=m2m
