What is the difference between predefined functions and user defined functions?
Predefined functions are built-in functions provided by a programming language or software application for common tasks, such as mathematical calculations or string manipulation. User-defined functions are functions created by the programmer to perform specific tasks tailored to the program's requirements. Predefined functions are readily available and can be used without additional coding, while user-defined functions require the programmer to define the function's behavior and implementation.
How is logarithmic functions as inverses of exponential?
An inverse of a function is found by swapping the x and y variables. For example: the straight line function y = 2x, has an inverse of x = 2y. This can be rearranged into y = x/2. Now take the function y = ex. The inverse is: x = ey. Unfortunately, there is no easy way to rearrange this to be y = {something}. So the logarithm function was created to handle this, and now the function {x = ey} can be written as y = ln(x).
Differences between user define function and uild in?
The person who created them.For example, you don't have to write an 'sprintf'function, because you already have it in the standard libraries.
When is a relation also a function?
A relation is also a function if each member of the domain (or x-coordinate) is paired with only one member of the range (or y-coordinate). If the relation is a set of ordered pairs that consists of real numbers a graph can be created to visualize the relation. If a vertical line can be drawn and only crosses or intersects the graph at one point then the relation is also a function.
What is the function of X plane?
X planes serve as functions for experiment and evaluation testing in the United States. They also serve as ideas for new technologies and areodynamic concepts. X planes have been built and tested for a wide array of experimental testing evaluations such as the X-1 Bell Aircraft plane built for high speed and altitude testing in 1946. It was the first plane to break the sound barrier. The X-23 Prime Martin Marinetta created in 1966 tested the atmospheric re-entry effects spacecraft and other potential aircraft in later years.
