WebThe tan of the sum of angles a and b is equal to the quotient of the sum of the tangents of angles a and b by the subtraction of the product of tangents of angles a and b from one. tan ( a + b) = tan a + tan b 1 − tan a × tan b. The above mathematical equation is called the tangent of angle sum trigonometric identity in mathematics. Webtan(165) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.
