WebMar 26, 2016 · The same type of factoring that algebra uses to solve equations is a great help in solving trigonometry equations. The only trick with the trig equations is to recognize that instead of just x' s, y' s, or other single-letter variables, trig variables such as sin x …
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. pop sherry clipsWebExample 4: Solve for x:sin2 x sin x 2 0, 0d x 2S.
