Review the steps of the proof. Tangent (StartFraction 3 pi Over 4 EndFraction minus B)

Step 1: Equals StartStartFraction tangent (StartFraction 3 pi Over 4 EndFraction) minus tangent B OverOver 1 + tangent (StartFraction 3 pi Over 4 EndFraction) tangent B EndEndFraction

Step 2: StartFraction negative 1 minus tangent B Over 1 minus tangent B EndFraction

Step 3: StartFraction negative 1 minus tangent B Over 1 + (negative 1) tangent B EndFraction

Step 4: Equals negative StartFraction 1 + tangent B Over 1 minus tangent B EndFraction

How must the proof be rearranged for the steps to logically follow each other?

Step 2 should be the last step.
Step 3 should be the last step.
Steps 2 and 3 must be switched.
Steps 3 and 4 must be switched.
