WebMar 24, 2024 · Example 14.5.1: Using the Chain Rule Calculate dz / dt for each of the following functions: z = f(x, y) = 4x2 + 3y2, x = x(t) = sint, y = y(t) = cost z = f(x, y) = √x2 − y2, x = x(t) = e2t, y = y(t) = e − t Solution a. To use the chain rule, we need four quantities— ∂ z / ∂ x, ∂ z / ∂ y, dx / dt, and dy / dt: ∂ z ∂ x = 8x dx dt = cost ∂ z ∂ y = 6y WebFirst, we would like to prove two smaller claims that we are going to use in our proof of the chain rule. (Claims that are used within a proof are often called lemmas .) 1. If a function is differentiable, then it is also continuous.
