‘Why Did We Ever Learn Trigonometry In School?’ This Man Has The Answer!

It sure had a great deal of importance during the school days- but as people grew up, the reason why every student was made to practice Trigonometry turned into one of the most asked questions– but not anymore– or so can be said based on this man’s video! A clip was recently shared on social media, where a man was seen addressing engineers while explaining why students were made to learn Trigonometry formulas and practice their questions in schools. The clip showed the man recalling the formula while also applying it practically on a machine.The explanation went on for quite a few seconds, which was long enough to not only impress mathematicians and engineers, but also the rest on social media. The internet soon began to joke about how math would

have been their “favourite” if the man in the video had been their teacher. Many also loved the man’s teaching and called him better than many professors.For those not aware, Trigonometry is one of the most interesting and tough branches of mathematics.

Internet’s reactions: “Reminds me of mechanical workshop days. All the fitters and turners are taught this. But instead of actually making them understand the concept, templates are provided explaining how to work for each job. Very few people, like this gentleman here, learn the overall concepts,” a user said.ALSO READ: 'Faahhh..LOL': When Gen Z Professors Check Papers; Internet Is Losing It | WATCH “How is he able to calculate hypotenuse?
