Homework Statement
(secx+1)/(sin2x) = (tanx)/2cosx-2cos2x)
Homework Equations
The Attempt at a Solution
Left Side
((1+cosx)/cosx)/2sinxcosx
((1+cosx)/cosx) x (1/2sinxcosx)
cancel the a cosx from both to get
(1/2sinxcosx)
This is all I could manage with left side so I tried right side
Right Side
(sinx/cosx)/2cosx-2cos2x)
I'm stuck here. I've been trying to find something to change the denominator of the Right Side but I can't think of anything that will work. If someone could let me know where I am going wrong it would be greatly appreciated!
