Deduce trignometric identity 6B (tan A- tan B) Identity 6B: tan (A - B) = 1 + tan Atan B Using sin (A-B) = sin A cos B - cos A sin B and cos (A-B) = cos Acos B + sin A sin B: tan (A-B) sin (A-B) cos (A-B) II now divide all terms by cos A cos B: tan (A-B) = therefore: tan (A-B) = (tan A- tan B) 1 + tan A tan B
