So Q4 : Have you drawn the graph?

You need to find the area between the sine graph and the x-axis. What method have you learnt for finding the area under curves?

Please post all of your thoughts with these questions. Even if you think they're stupid or insignificant.

It helps if you stay positive and don't learn things with an already defeated mindset.
