I got an answer after many tries. #csc^2x# can be converted into #1/sin^2x# according to the reciprocal identities and #1+tan^2x# can be converted into #sec^2x# according to the Pythagorean identities, and then convert that into #1/cos^2x# because its the reciprocal.
Explanation: If we write cot(x) as 1 tan(x), we get: cot(x) +tan(x) = 1 tan(x) + tan(x) Then we bring under a common denominator: = 1 tan(x) + tan(x) ⋅ tan(x) tan(x) = 1 + tan2(x) tan(x) Now we can use the tan2(x) +1 = sec2(x) identity: = sec2(x) tan(x) To try and work out some of the relationships between these functions, let's represent the
