Question

Use basic identities to simplify the expression.

cot θ sec θ sin θ

Answer 1

\[\cot=1/\tan\]
\[\tan=sin/cos\]
\[sec=1/cos \]

Answer 2

Ok, can you explain further?

Answer 3

Use the first 2 equations to get \[cot=cos/sin \]

Answer 4

Ok

Answer 5

So is it cos/sin times 1/cosx times 1/cscx ???

Answer 6

@henpen

Answer 7

Ok so it's csc^2x

Answer 8

\[\frac{\cos}{\sin}\sin \frac{1}{\cos}=1\]

Answer 9

So is it csc^2x ? @henpen

Answer 10

Sorry for my last post, I forgot it was sin.
No, it's 1 I think

Answer 11

Oh

Answer 12

cot θ sec θ sin θ
(cos θ/sin θ) (1/cos θ) sin θ

Answer 13

Oh ok got it, thanks so much :)
