The trigonometeric functions are all periodic, that is they repeat thier form at regular intervals. sin, cos, sec and csc have period 2Pi, whereas tan and cot have period Pi. sin and cos are bounded ...

There are three main trigonometric functions - Sine θ (sin θ), Cosine θ (cos θ) and Tangent θ (tan θ). Sin θ - Ratio of Perpendicular to Hypotenuse Cos θ - Ratio of Base to Hypotenuse Tan ...

Given a function f(x), and two points on the curve (a, f(a)) and (b, f(b)) the line joining these two points is called a secant line of f. (Not to be confused with the trigonometric secant (sec) ...
