Question

Simplify into 1 term:
[((sin(x-y))/(cos(x-90)sin(90-y)))-(cos2x + sin2xsinxsecx)] cotx
the numbers are in degrees and sorry if I confused things with the parentheses!

Answer 1

aye is that cos(2x/0 r cos ^2 x

Answer 2

cos(2x) sry i meant

Answer 3

\[(\frac{\sin(x-y)}{\cos(x-90)\sin(90-y)}-\cos2x+\sin2xsinxsecx)cotx\]is this it?

Answer 4

sorry! yest this is and how do you know it is cos(2x)?

Answer 5

there are parentheses between the nrgative and cos2x

Answer 6

*negative

Answer 7

Most probably it's wrong :|

Answer 8

this is what I got but one term only :(

Answer 9
