How to solve trig equations by factoring
WebThe three trigonometric equations formulas are as follows: For any real numbers x and y, sin x = sin y implies x = nπ + (-1) n y, where n ∈ Z. For any real numbers x and y, cos x = cos y implies x = 2nπ ± y, where n ∈ Z. If x and y are not odd multiples of π/2, then tan x = tan y implies x = nπ + y, where n ∈ Z.
