Trigonometry is a part of mathematics that is mainly about triangles. It is the study of triangles and its angles. Apart from triangles, trigonometry also deals with circles and more. Trigonometry was understood to define relations between elements of a triangle. In a triangle, there are six basic elements: 3 sides and 3 angles. Trigonometry is a methodology for finding some unknown elements of a triangle provided the data includes a sufficient amount of linear and angular measurements to define a shape uniquely.

**Trigonometry Formulas** includes formulas to calculate the sine, cosine, tangent, secant, co-secant and co-tangent of a right triangle. If length of the base side and the perpendicular side of the right triangle are given, then the sine, cosine, tangent, secant, co-secant and co-tangent values of the triangle can be calculated using the trigonometric formulas.

Below you can see a list of formulas under trigonometry.
