Hello, what is the identity from part (i)?
part (i) isnt related, it is just "show that sin(alpha + beta) + sin (alpha-beta) /cos (alpha + beta) + cos(apha - beta) = tan alpha
You'll need part i to do part v... If you didn't mention it upon Yong's request, we wouldn't be able to help for that
okay, got answer uploaded already.... HaHa... must give the identity . Otherwise, very, very long......
Exactly...
