If y = sin x and
Given y = sin x and x changes from to.
Let so that
On differentiating y with respect to x, we get
When, we have.
Recall that if y = f(x) and Δx is a small increment in x, then the corresponding increment in y, Δy = f(x + Δx) – f(x), is approximately given as
∴ Δy = 0
Thus, there is approximately no change in y.
