Answer 1

@Directrix

Answer 2

Why don't you lead us off on #12?

Answer 3

okay, i'll send you a picture of my work

Answer 4

hint: take common factor of the left-side
bear in mind that \(\bf sin^2(\theta)+cos^2(\theta)=1\)

Answer 5

hmm

Answer 6

@Directrix

Answer 7

what would you get if you take common factor on the left-side? \(\bf 2sin^3(\theta)cos(\theta)+2sin(\theta)cos^3(\theta)=sin(2\theta)\)

Answer 8

you're supposed to factor

Answer 9

well.. you're meant to "verify" the identity, if factoring works, sure
if common factoring works, then is fine too

Answer 10

you're doing fine, but i really diretix help if you dont mind

Answer 11

k
