Course Description

Often, we come across functions that we do not know how to evaluate without having qualitative knowledge of the input value. For example, $\sin(x)$ , $\max(x, y)$ ¹ , and $|x|$ .

For example, how do we compute $\min(x,y)$ without knowing beforehand what $x$ and $y$ are, using only a basic calculator²?

This question, along with many others, will be answered in this short course.

$\max$ stands for maximum. $\max(x,y)$ will always return the larger value out of $x$ and $y$ . Similarly, $\min(x,y)$ (minimum) returns the smaller of $x$ and $y$ .↩
For the purpose of this course, we will assume our calculator to have the following capabilities:
- Addition, Subtraction, Multiplication, and Division
- Exponentiation
  - including square roots
- Floor and Ceiling
These basic capabiities will enable us to construct other, more complex capabilities.↩
