Find the first partial derivative with respect to a
∂b∂m=a1
Simplify
m=ab
Find the first partial derivative by treating the variable a as a constant and differentiating with respect to b
∂b∂m=∂b∂(ab)
Use differentiation rule ∂x∂(g(x)f(x))=(g(x))2∂x∂(f(x))×g(x)−f(x)×∂x∂(g(x))
∂b∂m=a2∂b∂(b)a−b×∂b∂(a)
Use ∂x∂xn=nxn−1 to find derivative
∂b∂m=a21×a−b×∂b∂(a)
Use ∂x∂(c)=0 to find derivative
∂b∂m=a21×a−b×0
Any expression multiplied by 1 remains the same
∂b∂m=a2a−b×0
Any expression multiplied by 0 equals 0
∂b∂m=a2a−0
Removing 0 doesn't change the value,so remove it from the expression
∂b∂m=a2a
