Sorry, we don't have access to this program. If you write out a specific question, we can answer it for you.
The same as in any other math class. All functions are relations but all relations are not functions. A function must have only one 'answer' in the range for each value of the domain. Relations are just pairing of numbers with no such restriction on the range.
Functions are our way of expressing a relation between two sets, which is of fundamental importance to all of math. In fact, one could argue that there would be no math, only numbers, if there weren't any relations between the numbers.
It means that one of them depends on the other. When you change one, the other usually changes in some way. Many relations are functions like y=3x2 - x + 7. Other relations, such as x2 + y2 = 25, are not functions, but they are still relations.
they look like arithmetic and geometric patterns in math
Well, what produces math? Answer: patterns and reasoning. So there you have it.

They can have.
At the top of your program: import math or from math import * The second one imports all math functions, like fact() for factorial.

He memorized tables of functions, exponential functions, logarithmic functions, etc, ... try looking up "handbook of mathematical functions"
