The idea: Roughly, the limit is the value that f(x) should assume when x = x0. It is a prediction based on nearby x-values. Less roughly, to say the limit is L, you have this situation: The goal is to make f(x) close to L, as close as you might want.

Then, what does x0 mean in math?

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Likewise, what is a calculus function? DEFINITION. A function is a rule or correspondence which associates to each number x in a set A a unique number f(x) in a set B. The set A is called the domain of f and the set of all f(x)'s is called the range of f.

Also to know is, what does a stand for in calculus?

h is a variable commonly used in the limit definition of a derivative: lim(h →0) ((f(x + h) - f(x))/h) a is a variable commonly used to represent the lower limit of a definite integral: the integral from a to b of f(x)

What does Lim mean in calculus?
