Tangent Addition Formula. In trigonometry, the tangent addition formula is referred to as the tan (A + B) formula for the compound angle (A+B). It is used when the angle for which the tangent function value is to be determined is supplied as the sum of any two angles. It may alternatively be written as tan (A + B) = sin (A + B)/cos (A + B.

Voiceover: In the last video we proved the angle addition formula for sine. You could imagine in this video I would like to prove the angle addition for cosine, or in particular, that the cosine of X plus Y, of X plus Y, is equal to the cosine of X. Cosine of X, cosine of Y, cosine of Y minus, so if we have a plus here we're going to have a.

Solution. By recognizing the left side of the equation as the result of the difference of angles identity for cosine, we can simplify the equation. sin(x)sin(2x) + cos(x)cos(2x) = √3 2 Apply the difference of angles identity. cos(x − 2x) = √3 2. cos( − x) = √3 2 Use the negative angle identity. cos(x) = √3 2.
