I am going to work from the left side of the equation. (csc-sin)
Step 2-Back to basics- turn all figures into cosine and sine.csc- >1/sinSin -> sin/1
Step 3Least common denominator- sin
1/sin sin2/sin
Step 4Subtract- 1/sin sin2/sin
1-sin2/sin
Step 5Trigonometric identities 1-sin2 = cos2
Substitute-cos2/sin
Step 6Simplifycos2/sin = (cos)(cos)/sin
Cos/Sin = tan
You will be left with one cos and a tanWhich gives you your answer of CosTan
