Trigonometry is a branch of mathematics that deal with angles, lengths and heights of triangles and relations between different parts of circles and other geometrical figures.

## Trigonometry Functions Formulas

Maths Formulas — Trigonometric Ratios and identities are very useful and learning the below formulae help in solving the problems better. Trigonometry formulas are essential for solving questions in Trigonometry Ratios and Identities in Competitive Exams.

## Super Hexagon for Trigonometric Identities

These formulas relate lengths and areas of particular circles or triangles. Length of an arc.

The most important formulas for trigonometry are those for a right triangle. The trigonometric properties are given below Magical Hexagon for Trigonometry Identities. Clock Wise:.

## Trigonometry Formulas

Counterclock Wise:. A lot of trigonometry formulas are based on the signs of trigonometric ratios, based on the quadrants they lie in.

Therefore it becomes extremely essential for us to understand how trigonometric ratios get the positive or negative sign. The sign is based on the quadrant in which the angle lies. So let us see how signs change with respect to the quadrant they lie in.

So the above will be negative. So there are 2 important things to remember-.

After looking at the trigonometric ratios, let us move on to trigonometric identities, which are the basics of most trigonometry formulas.
