Web- You are solving for the HYPOTENUSE. Therefore you need the trig function that contains both the OPPOSITE and the HYPOTENUSE, which would be SINE, since sin = OPPOSITE / HYPOTENUSE. "Let's input the value into the equation." sin (deg) = … 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.
