In this video I will cover how to evaluate the six trigonometric functions given a right triangle. We will find the missing ...

Learn about the Pythagorean theorem. The Pythagoras theorem is a fundamental relation among the three sides of a right ...

Pythagoras’ theorem can also be used to find the length of another side of a triangle using the hypotenuse. The square on the hypotenuse subtracted by the square on another side is equal to the square ...

The Pythagorean Theorem—discovered by the Greek mathematician Pythagoras in the 6th century BCE—is a cornerstone of mathematics. Simply stated as a 2 + b 2 = c 2, the theorem posits that the sum of ...

An understanding of how to use Pythagoras’ theorem to find missing sides in a right-angled triangle is essential for applying the theorem in different contexts. (3,1) is the coordinate that is 3 along ...

Two high school students proved the Pythagorean theorem in a way that one early 20th-century mathematician thought would be impossible: by using trigonometry. Calcea Johnson and Ne’Kiya Jackson, both ...

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school. When you ...
