Question

Please Help!!
If x = 7 sin θ, write the expression θ/2 − sin 2θ/4 in terms of just x. (Simplify the double angle using a double-angle identity.)

Answer 1

did you make sure you put all the ( ) in the right place?

Answer 2

see my post on your previous question

Answer 3

I did! I did! it was wrong....

Answer 4

i got it
we did the whole thing wrong

Answer 5

I don't see how we did

Answer 6

unless again you didn't mean \[\frac{\theta}{2}-\frac{\sin(2 \theta)}{4}\]

Answer 7

did you mean \[\frac{\theta}{2}-\sin(\frac{2 \theta}{4})?\]

Answer 8

yes but the way i inserted the info into this problem was wrong
