## High School Algebra: Well-Known Equations - Chapter Summary and Learning Objectives

This chapter covers several well-known mathematical equations, including the theory of relativity, the value of e and Euler's identity. You'll learn about Isaac Newton's formula for the force of gravity, and see how mathematical formulas are used in everyday life; for example, you'll find out how to calculate monthly loan payments using an equation.

By the end of this chapter, you should be able to:

• Use the Pythagorean theorem to determine the length of one side of a right triangle.
• Find the diameter and circumference of a circle using pi.
• Explain why Fermat's Last Theorem was one of the world's toughest math problems.
• Solve equations using the quadratic formula.
