AP PHYSICS: The Pythagorean Theorem
Trigonometric functions establish useful relationships between the sides of a right triangle that exists within the perimeter ( circumference ) of a unit circle. We are now ready to see how the Pythagorean Theorem does this as well. In the right triangle below, the “ legs “ around the right angle are equal in length,Continue reading “AP PHYSICS: The Pythagorean Theorem”
