Use the trigonometric relations and identities.
Trigonometric identities are trigonometric equations that are always true.
They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.
There are several topics under the broad category of trigonometry. * Angle measurements * Properties of angles and circles * Basic trigonometric functions and their reciprocals and co-functions * Graphs of trigonometric functions * Trigonometric identities * Angle addition and subtraction formulas for trigonometric functions * Double and half angle formulas for trigonometric functions * Law of sines and law of cosines * Polar and polar imaginary coordinates.
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
There are three types of trigonometric functions, they are: 1- Plane Trigonometric Functions 2- Inverse Trigonometric Functions and 3- Hyperbolic Trigonometric Functions
Use the trigonometric relations and identities.
The sine and cosine are both trigonometric functions. Trigonometric calculations are used in many branches of engineering.
TRIGONOMETRIC FUNCTIONS OF ANY ANGLE
Yes, but it is called a hyberbolic trigonometric function
Use trigonometric identities to simplify the equation so that you have a simple trigonometric term on one side of the equation and a simple value of the other. Then use the appropriate inverse trigonometric or arc function.
Trigonometric identities are trigonometric equations that are always true.
Just as with any other identity, a trigonometric identity is a trigonometric statement (other than a definition), which is true for all values of the variable or variables.
