The term tan(a ± b) refers to the tangent of the sum or difference of two angles, a and b. This identity is part of a larger set of trigonometric identities that allow for the expression of the tangent of combined angles in terms of the tangents of the individual angles. These identities are crucial for simplifying expressions and solving equations that involve trigonometric functions.
