Very well explained, thank you for this video. It's been 16 years since I did GCSEs and now i'm looking to go back and do A Level Physics, which needs trig knowledge for vectors (among various other things i'd imagine). These videos have been invaluable in revising what I knew (and got an A in!) all those years ago. THANK YOU :)

A is always hypotenuse

10:44 can you use tan as there is oppisite angle and you want to find out adjecent to 55 angle

[@ajmrf]

no because soh cah toa is only used in right angled triangles. the h in soh and cah means hypotenuse which implies its only for right angled triangles

[@572IA]

The area formula is 1/2 x a x b x sin C, and because C is the sine angle in the formula, that means the angle is on C

isn’t is x over 6 not 6 over sin what r u doing ???

[@theblackhat9769]

1:20 But why do we need the opposite

[@amirrthan]

because the adjacent is not need as it will give the wrong answer

[@amirrthan]

That's just how the rule follows. You aren't using the opposite and adjacent because you want to use the sine function, rather you are using the sine function because in this question you have values (or desired unknowns) that require the sine rule. Namely the opposite and the hypotenuse.
