Trigonometric table
The Trigonometrical ratios table will help us to find the values of trigonometric standard angles. The standard angles of trigonometrical ratios are 0°, 30°45°, 60 ° . Values of table find by unit circle. Table of values of the 6 trigonometric functions sin (x), cos (x), tan(x), cot (x), sec ( x) and csc (x) for […]
Trigonometric ratios conversion table
Pythagoras identities are use to convert trigonometric ratio from one form to another. Also we use right angle triangle for conversion. Conversion of trigonometric ratio
Circular measure -2
The radian is a unit of measurement angle . Therefore, this unit is used in many topics likewise sector , angles . Parts of the mathematics area which include circular measure and more often, the branch of angle measurements where pi (Π) is used. Therefore, radian use to measure arc length, chord length, area of sectors of a circle and many others. […]

Double angle Identity
Double‐Angle and Half‐Angle Identities. Because sin x is positive, angle x must be in the first or second quadrant. The sign of cos 2 x will depend on the size of angle x. A double–angle function is written, for example, as sin 2θ, cos 2α, or tan 2x, where 2θ, 2α, and 2x are the angle measures and the assumption is that you […]
Area of triangle
Area of Triangles Without Right Angles. There are several ways to find the area of a triangle. When we know the base and height it is easy. therefore the area also equals half of ab sin C. Area of triangle
Trigonometric Equation
Solving trig equations use both the reference angles and trigonometric identities The general method of solving an equation is to convert it into the form of one ratio only. Then, using these results, hence, we can obtain solutions. Trigonometric equation
