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.
