How to solve trig equations for exact values
WebThe three trigonometric equations are Sinθ = Sinα, Cosθ = Cosα, Tanθ = Tanα. The 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. WebOct 28, 2024 · Overview.
