Why is the cosine rule always taught after Pythagoras' Theorem? I mean, it makes to me more sense to teach about triangles in general, and then tell the students: "What happens when we plug to cos the number 90? It equals 0! What does it mean?" _Transition_ "And this is what is called in mathematics Pythagoras' Theorem"
you explain everything so well, kinda wish you were my math teacher instead of the pathetic one I currently have lol
These videos are just incredible!
Thank you sir! I never noticed that Pythagoras theorem was a part of the cosine rule(>~< )
these childrens not appreciated the talent of mr woo to educate them! be quite! i thank you mr woo sir you are helping me unbelievibly god bless you
i don't understand anything in class but eddie makes it understandable
Sir you are the great teacher mashallah
If every teacher were like u everyone would like math
Magic !!
It just works

Because you can teach Pythagoras without having to teach any trigonometry. All you need is to know area of triangles and squares.
Pythagoras' theorem is very easy to remember and use and doesn't require any trigonometry, plus it gives students good experience working with surds.
