Opposite sin hypotenuse q hypotenuse csc opposite q adjacent cos hypotenuse q hypotenuse sec adjacent q opposite tan adjacent q adjacent cot opposite q Unit circle definition For this definition q is any angle.
. Definition of the Trig Functions Right triangle definition For this definition we assume that 0 2 p. This means that the ratio of any two side lengths depends only on θThus these six ratios define six functions of θ which are the trigonometric functionsIn the following definitions the hypotenuse is the length of the side opposite the right angle opposite represents the side. The idea of 6 basic trig ratios in a unit Circle.
So if is a xed number and is any angle we have the following periods. All the ratios have different values and functions. A 1 2 absin 2.

In the unit circle chart there are different ratios exist. Formula of Trigonometry Sin Cos Tan Cot Sec Cosec. Ptolemys identities the sum and difference formulas for sine and cosine.
Sine tangent cotangent and cosecant are odd functions while cosine and secant are even functions. Sine cosine secant and cosecant have period 2 π while tangent and cotangent have period π. Sin sin sin Law of cosines 34.
The chart has Sin Sec Tan Cos Csc and cot ratios. Trigonometry Charts and Trigonometric Ratios Tables. This can be simplified to.
A2c2 b2c2 c2c2. Sin2t cos2t 1. Dividing through by c2 gives.
Among other uses they can be helpful for simplifying trigonometric expressions and equations. If the acute angle θ is given then any right triangles that have an angle of θ are similar to each other. Calculate Height and Distance Heights and Distances Formula.
Cos θ Adjacent SideHypotenuse. Trigonometric identities are equations that are used to describe the many relationships that exist between the trigonometric functions. Differentiation Formula for Trigonometric Functions.
The key Pythagorean Trigonometric identity are. Identities for negative angles. Tan θ Opposite SideAdjacent Side.
It consists of trigonometric ratios sine cosine tangent cosecant secant cotangent. A2 b2 c2 2 b c cos b2 a2 c2 2 a c cos c2 a2 b2 2 a b cos Area of triangle 35. Many geometric calculations can be easily figured out using the table of trigonometric functions and formulas as well.
By using a right-angled triangle as a reference the trigonometric functions and identities are derived. Ad Choose from a Wide Variety of Trigonometric Identities Lessons. It may works as an input value chart while accessing the trigonometry functions.
