7.2 Sum and Difference Identities - Precalculus OpenStax
WebSum and Difference Formulas for Tangent In this section, we will prove the sum and difference identities for the tangent function. We know that tangent function can be written as the ratio of the sine and cosine, that is, tan A = sin A / cos A. So, we can write tan (α + β) as, tan (α + β) = sin (α + β) / cos (α + β) WebTan of Sum and Difference of Two Angles sin ( α + β) = sin α cos β + cos α sin β sin ( α − β) = sin α cos β − cos α sin β The cosine of the sum and difference of two angles is as follows: cos ( α + β) = cos α cos β − sin α … shelley morgan nfr
