From the name itself, a unit circle is a circle with a unit radius. Circles are closed geometric figures without sides or angles. A unit circle has all of the properties of a circle, and its equation is also derived from the equation of a circle. Furthermore, a unit circle is useful for determining the … Read more

## Negative Exponent Rule: Definition, Explanation & Examples

The negative exponent Rule tells us that the power of a number is negative and it applies to its reciprocal. When a number is multiplied by itself, it is called an exponent. For example, 32 = 3 × 3. When we have positive exponents, it is easy to multiply the number (base) by itself, but what … Read more

## Factor Theorem & Remainder Theorem: Explanation, Facts, and Examples

The factor theorem establishes a relationship between factors and zeros of a polynomial in algebraic mathematics. As an application of the polynomial remainder theorem, the Factor theorem is unique. Thus the factor theorem states that a polynomial has a factor if and only if: The polynomial x – M is a polynomial f(x) if and … Read more
