Answer 2

@Zarkon

Answer 3

the question is unclear. and I give you medal for free. heheh, I don't know how to solve

Answer 4

oh thanks!

Answer 5

oh thanks!

Answer 6

Trig identities,\[\cos^2\theta-1=\sin^2\theta\]

Answer 7

nope

Answer 8

it wants me to simpify

Answer 9

Why not?
and that is simplified

Answer 10

\[-\cos^2(aht^2e)\]

Answer 11

Oh I see my mistake.. again

Answer 12

yea \[-\cos^2\theta \]
sorry about that :/

Answer 13

redo

Answer 14

@Luigi0210

Answer 15

@lala2 he gave you the formula, you replace and figure out the answer. 1= sin^2 +cos^2

Answer 16

what about this one
sec(theta)sin(theta)cot(theta)

Answer 17

\[\sec \theta*\sin \theta*\cot \theta=\frac{ 1 }{ \cos \theta }*\sin \theta*\frac{ \cos \theta }{ \sin \theta }=\frac{ \sin \theta }{ \cos \theta }*\frac{ \cos \theta }{ \sin }\]

Answer 18

*sin(theta)
