Inequalities

Hi guys! I hope we are good?

In this short video I teach about inequality. We are used to equations in most mathematical questions. But there are scenarios where the LHS is not equal to the RHS. Then it becomes an inequality.

Sine rule and Cosine rule

Hi guys! Today I bring you an excerpt from our 5th video in the trigonometry playlist.

We learn here that for triangles that are not right-angled, we can use the sine rule or the cosine rule in solving them.

Enjoy the video.
