When it comes to Maths, it surely isn't everyone's favourite subject. But we do wish that someone taught us difficult things like trigonometry in a fun way. Notably, that did happen in the United States, where an Indian teacher found a musical way to make students memorise the material for trigonometry.
Now a video of him is trending all over the internet, where he's seen teaching trigonometry in an unconventional method and his students are repeating after him in the same way.
Though this is an old video which was shared on Facebook back in 2012, it is again going viral now for all the right reasons.
