What is a closed-form function? What can we say about such functions?
The meaning of a closed-form function and a feature of closed-form functions.
The given function is a closed-form function.
The definition of a closed-form function:
A closed-form function is obtained by joining constants, exponential functions, radicals, power of x, logarithms and trigonometric functions to form a single mathematical formula with the help of arithmetic operations and composition of functions.
The feature of closed form functions is that all the closed-form functions are continuous in their domain.
If is lies in a closed function’s domain, then
Consider the limit is .
Here, is a closed-form function and lie in its domain
