Yes, but it is called a hyberbolic trigonometric function
It is a trigonometric function. It is also continuous.
An antitrigonometric function is another term for an inverse trigonometric function.

A reciprocal trigonometric function is the ratio of the reciprocal of a trigonometric function to either the sine, cosine, or tangent function. The reciprocal of the sine function is the cosecant function, the reciprocal of the cosine function is the secant function, and the reciprocal of the tangent function is the cotangent function. These functions are useful in solving trigonometric equations and graphing trigonometric functions.
It is just a name invented by mathematicians.
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.
Trigonometry is the study of the relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships.
Yes, but it is called a hyberbolic trigonometric function
They are true statements about trigonometric ratios and their relationships irrespective of the value of the angle.

An arc-hyperbolic function is an inverse hyperbolic function.
Trigonometric functions are defined from a numeric domain to a numeric range. So the input number determines whether or not the function is defined for that value and, if so, what the value of the function is.
