hi i know its a bit late but this was really helpful thank you i just had a question like with cosine rule as the equations are different in question 1 the equation differs from question2 why is that? Also with the sine rule there is a point where you have to square root but in the first question we did not square root why is that ? I feel like there is some sort of difference between the two i would be really glad if you briefly elaborate on this comment thank you
forget the original letters that are there, they confuse you. The angle is always going to be cos A so any side opposite that is always a. side b and c can be anywhere but a is always opposite ANGLE A
If you want an honest answer: Study this, and you’ll do well at a level maths Do well at a level maths, and you’ll go to a good university doing a good (quantitative) course Do well at university, and you’ll make above average money Think about this long term
i really wrote out each triangle in the beginning, only for him to solve others
Bahahaha
I enjoy how you explain this subject. Thanks, sir.
Thanks for the vid. Really helps.
It did? I already knew this stuff

in question 1 they were finding the angle in question 2 they were finding the length
aren’t the letters apposite each other so C would be opposite c, B would be opposite b and A would be opposite a?

Many Thanks!
the real question is, where did you get the calculator???
How is this going to help me become rich

why you flipped a/sin x to sin x/a , is there some rule or your mistake ?
I love you ❤
