Kristian Burke#38 verifying equationsStep 1Equations- csc-sin = coscot

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
