I can be really crap at Math, so I will post questions here which I need help with.
First Question![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
1 + cot^2 alpha could become cosec^2 alpha but how do you simply the top properly with 2cot alpha? Should you just convert the top into cos/sin + cos/sin??
