1.2.6 Example 

The diagram shows the displacement-time graph for a body performing simple harmonic motion. Suggest in terms of period T the following
(a)    range of time where the velocity and acceleration are in same direction.
(b)    range of time where the velocity and acceleration are in opposite directions

suggested answers

$\genfrac{}{}{0.1ex}{}{T}{4}<t<\genfrac{}{}{0.1ex}{}{T}{2}and\genfrac{}{}{0.1ex}{}{3T}{4}<t<T$

$0<t<\genfrac{}{}{0.1ex}{}{T}{4}and\genfrac{}{}{0.1ex}{}{T}{2}<t<\genfrac{}{}{0.1ex}{}{3T}{4}$
