- The function y = sin x completes one period on the interval 30, 2π4, the function y = sin 2x completes two periods, the function y = sin (x/2) completes half a period, and so on. Is there any relation between the number of periods y = sin mx completes on 30, 2π4 and the slope of the curve y = sin mx at the origin? Give reasons for your answer.true or false? Continuous functions have a tangent line at all points.THEOREM 3.14 Derivative Involving Absolute ValueIf $u$ is a differentiable function of $x$ such that $u \neq 0$, then$$\frac{d}{d x}[\ln |u|]=\frac{u^{\prime}}{u}$$
