change everything in terms of sin and cos
take lcm , simplify and then factorise using
a³ - b³ identity and then cancel off sinx-cosx
then split into two terms

prove that (cotA+cosecA-1)/(cotA-cosecA+1)=cosecA+cotA -----> (problem on trigonometry )
Prove that (tanxsinx) / (tanx+sinx) = (tanx-sinx) / (tanx sinx) -----> (problem on trigonometry )
find exact value of tan[22½ °] or tan (pi / 8 ) -----> (problem on trigonometry )
conditional identity : If A+B+C=π,
prove that: sinA+sinB+sinC = cot(A/2).cot(B/2) [sinA+sinB-sinC] -----> (problem on conditional identity (trigonometry) )
