A)cot theta
B)cot theta
C)tan thetacot theta
D)tan thetasec^2theta
just tell me what I need to know to set it up

Thank you for using the Jiskha Homework Help Forum. If it's Math, I doubt I can help you, but try these sites:

if you ar having issues read it again or 3 times . you can also try to contact a friend

trig identities are like in a different language for me. can I please get at least 1 step to get started. I looked at all the sites about it but if I don't understand what im looking at it does no good, I know how to read I just don't get it.

Notation: sin(theta) = s; cos(theta) = c.
Then tan(theta) = s/c and
sec(theta) = 1/c
We can write:
s/c  1/(cs) = (s^2  1)/(cs) = c/s = Answer A 
I understand that a little thank you sooo much for explaining it.
