Question: Show that the difference quotient for f(x) = sin x is given by f(x + h) - f(x) sin(x + h) sin x 1- cos

Show that the difference quotient for f(x) = sin x is given by

 f(x + h) - f(x) sin(x + h) – sin x 1- cos h sin x sin h = Cos X

f(x + h) - f(x) sin(x + h) sin x 1- cos h sin x sin h = Cos X
