Hi! I need to establish this: using the more basic trigonometric identities. I've tried all kinds of stuff for several hours without results. Any help would be highly appreciated!

Awesomesauce!! Thanks a bunch!
Alternatively write the right hand side as 1/cosx+sinx/cosx= (1+sinx)/cosx and then show that LHS-RHS=0 by putting on common denominator.
