Why is calculus important in math?
calculus allows people to give numerical values to the slopes of curves and gives us a way to find things like to maximum value of a function that is too large to graph or find the equation of the tangent line to a curve at a certain point.

What is an undefined term?
An undefined term is usually applied to a function (or a part) where for some values of the operands the function is not defined within the field in which it is defined. It may be defined in a bigger field. For example, division by zero is not defined anywhere. Square roots of negative numbers are not defined in the domain of Real numbers, but they are perfectly OK in the Complex field.
