Rationalism is the idea that humans are capable of using their faculty of reason to gain knowledge. This was a sharp turn away from the prevailing idea that people needed to rely on scripture or church …

Learn the difference between rational and irrational numbers, learn how to identify them, and discover why some of the most famous numbers in mathematics, like Pi and e, are actually irrational.

We'll learn how to simplify, multiply, and divide rational expressions, as well as add and subtract them—whether they're factored or not. We'll also dive into understanding the graphs of rational …

Divide one polynomial by another, and what do you get? A rational function! We'll analyze the family of rational functions, and we'll see some examples of how they can be useful in modeling contexts.

Sal writes all the rational exponents as fractions. But can exponents be in decimal form? For example, x^ (-2.5) and x^ (-5/2), are both of them correct?

This topic covers: - Simplifying rational expressions - Multiplying, dividing, adding, & subtracting rational expressions - Rational equations - Graphing rational functions (including horizontal & vertical …

A rational number can be written as a ratio of two integers. Integers are: 0, 1, 2, 3, 4, etc. and -1, -2, -3, -4, etc. Pi is not an integer, so writing it as Pi/1 doesn't turn it into a rational number.

If we can write a number as a fraction that has both an integer numerator and an integer denominator, then it is rational. If we can't, then it is irrational. Repeating decimals are rational, because we can …

Video transcript - [Voiceover] So we have a nice little equation here dealing with rational expressions. And I encourage you to pause the video and see if you can figure out what values of x satisfy this …

Rational numbers are numbers that you can represent as a fraction or a decimal. For example, 3/2 would be a rational number because you can represent it as a fraction.
