Hello, I am having a bit of trouble solving this eqn: tan (x) + cot (x) = 2sec (x) For all angles between 0 and 360 degrees. Thank you! Max

Ah very clever! Thank you very much! Im now a but stuck on this: tan (x) + 3cot (x) = 5sec (x) Very similar but the cos^2 {x) + sin^2 (X) = 1 trick doesnt work?

Another clever little trick on line three, hadnt thought of that, thankyou very much! Now that ive seen these tricks i wont forget them!
