4. History behind the
Formula
Babylonians understood the connection between the
sides of a right triangle.
Babylonians figured out the relationship
approximately 1000 years before Pythagoras.
It was named the Pythagorean Theorem because he
is considered the first to have given proof that the
formula is true.
5. Terms and Definitions
Hypotenuse: The side
opposite of the right
angle.
Pythagorean Triples: It is
when all sides are
integer values. Example
3,4,5
6. When can it be used?
C
5
12
This formula can only be used with right triangles.
Two side lengths must be given.
11. Example of use for
Differentials
Car A is traveling west
at 40 mi/h and car B is
traveling north at 40 X
mi/h. Both are headed
for the intersection of
the two roads. At what Y
rate are the cars
approaching each
other when car A is 0.4
mi and car B is 0.3 mi
from the intersection?
12. Solution
Given Values
1. dx/dt=40 miles per hour
2. dy/dt=40 miles per hour
Solve for:
Dz/dt when x=.4, and y=.3
