Best ResponseYou've already chosen the best response.1and 1cos^2(x) = sin^2(x) as sin^2(x) + cos^2(x) = 1 this identity comes from the unit circle

Best ResponseYou've already chosen the best response.02 / sin(x) is like saying 2 times 1 /sin(x) which mean 2 times csc(x) or 2 csc(x) since csc = 1/sin(x)
