One of the simplest and most basic formulas in Trigonometry provides the measure of an arc in terms of the radius of the circle, , and the arc’s central angle θ, expressed in radians. The formula is easily derived from the portion of the circumference subtended by θ.

The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a right-angled triangle divided by another. For any angle " θ ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)
