Free math problem solver answers your trigonometry homework questions with step-by-step explanations.
The three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent.
Tangent. In a right triangle, the ratio of the length of the side opposite the angle to the length of the adjacent side. tan (θ) = Opposite Adjacent. π 2 + π n, n is an integer. (− ∞, ∞) Secant. The reciprocal of the cosine of an angle. sec (θ) = 1 cos (θ) π 2 + π n, n is an integer.
