Could anyone help on this trig identity? I have a quiz tomorrow and am unsure on this one.
(1/tanx-secx)+(1/tanx+secx)= -2 tanx
Any help is appreciated!
Can you walk me through this?
Here is what I got (didn't place any x's for visual purposes):
(tan+sec)/(tan^2-sec^2) + (tan-sec)/(tan^2-sec^2)
simplified that further to:
(tan+sec+tan-sec)/(tan^2-sec^2)
simplified even more to get:
(2tan)/(tan^2-sec^2)
Now I'm stuck. can you heLp?
thanks
