Review the proof of Tangent (A minus B) = StartFraction tangent A minus tangent B Over 1 + (tangent A) (tangent B) EndFraction.
tan(A – B) =
Step 1: Equals StartFraction sine (A minus B) Over cosine (A minus B) EndFraction
Step 2: Equals StartFRaction sine A cosine B minus cosine A sine B Over cosine A cosine B + sine A sine B EndFraction
Step 3: Equals StartStartFraction StartFraction sine A cosine B minus cosine A sine B Over blank EndFraction OverOver StartFraction cosine A cosine B + sine A sine B Over blank EndFraction EndEndFraction
Step 4: Equals StartFraction tangent A minus tangent B Over 1 + (tangent A) (tangent B)
To complete step 3, which expression must fill in each blank space?
