Question

dy
Find if
dx
(i) x + xy + xy + y = 4​

Answer 1

Answer:

Add Δx. When x increases by Δx, then y increases by Δy : y + Δy = f(x + Δx)

Subtract the Two Formulas. From: y + Δy = f(x + Δx) Subtract: y = f(x) To Get: y + Δy − y = f(x + Δx) − f(x) Simplify: Δy = f(x + Δx) − f(x)

Rate of Change.
