Which of the following equations are identities? cot x = cosx/sinx tanx = 1/cot x cscx = 1/cos x cscx = 1/sec x
more than one answer as well
@NewbieCarrot ??? There is no C, and the third one is not an identity...
Have you found the answer yet?
What I used to do was express everything in terms of sine and cosine.
identities or trigonometric identities?
no ._. and what? it can be as many as apply its not just one
@Mpost1994 I agree with you on this one. there's more than one answer
I believe C is the trig identity.
newbie..you don't know what you are talking about do you ._.
i think 1st and 2nd one are right.
C is wrong. cscx = 1/sinx
Sorry I messed up.
an identity is when the equation is exactly the same on both sides
and uh....is 4 one? ...cru its 4 am ..whatsthe answers ._.
if you look at the drawing i put cos over sin and that is cot

too tired to think ....guessed at 1 2 and 4 ...its just 1 and 2 ...thnx night.. smh
