Trigonometry goes back to ancient times. The first trigonometric table is attributed to Hipparchus of Nicaea.
There are three types of trigonometric functions, they are: 1- Plane Trigonometric Functions 2- Inverse Trigonometric Functions and 3- Hyperbolic Trigonometric Functions
It is a table that gives the cosines of angles, usually from 0 to 90 degrees in steps on 0.1 degree. These were used extensively for trigonometric calculations before the advent of computers.
Yes, but it is called a hyberbolic trigonometric function
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.
221 is theta (1)
PLEASE rephrase that. I don't speak broken

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.
