1. The problem statement, all variables and given/known data (secx+1)/(sin2x) = (tanx)/2cosx-2cos2x) 2. Relevant equations 3. 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!
