thats not what i am talking about, i am talking about proofs.
like proof that RS=LS by simplifying it
hi ahmedb Spoiler:
what did you multiply by 1-cosx?
y can't u use 1-sinx or anything else???
thats what confused me :S
when you multiply by 1-sin(x) you don't get anything pretty.by multiplying by 1-cos(x) you get 1-cos^2(x) which you should now is sin^2(x).another way to do this is to multiply the fraction on the RHS by 1+cos(x).
for the RHS why is it 1+cosx??
is there a method like a rule in which you have to follow?
You can also use
That means for this exercice:
