Trigonometric functions, exponential functions are two common examples.
Yes, but it is called a hyberbolic trigonometric function
TRIGONOMETRIC FUNCTIONS OF ANY ANGLE
It is a trigonometric function. It is also continuous.
An antitrigonometric function is another term for an inverse trigonometric function.
The trigonometric function of an angle gives a certain value The arc trigonometric function of value is simply the angle For example, if sin (30 degrees) = 0.500 then arc sine ( 0.500) = 30 degrees
Cotangent is a trigonometric function. It is the reciprocal of the tangent.
You only use the seccant trigonometric 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.
cot(A+B+C) is, itself, a trigonometric function, so the question does not really make any sense!
