Find the first partial derivative with respect to x
Find the first partial derivative with respect to a
∂x∂y=−12x2a
Simplify
y=−4x3a
Find the first partial derivative by treating the variable a as a constant and differentiating with respect to x
∂x∂y=∂x∂(−4x3a)
Use differentiation rule ∂x∂(cf(x))=c×∂x∂(f(x))
∂x∂y=−4a×∂x∂(x3)
Use ∂x∂xn=nxn−1 to find derivative
∂x∂y=−4a×3x2
Solution
∂x∂y=−12x2a
Show Solution
