Question

Which expression is equivalent to tan theta-sec theta/sin theta?
A)-cot theta
B)cot theta
C)tan theta-cot theta
D)tan theta-sec^2theta

just tell me what I need to know to set it up

Answer 1

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.

Answer 2

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

Answer 3

I understand that a little thank you sooo much for explaining it.

Answer 4

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