The Pythagorean theorem:
The theorem that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
<h2>The Pythagorean Theorem</h2><h3>Discoverer: Pythagoras</h3>
In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. These calculations were discovered just as a tool of the ancient civilization of Babylonians who used it to divide up farmland; this was roughly 1,000 years before the birth of the discoverer, Pythagoras, a Greek philosopher.
The formula comes like this:

Step-by-step explanation:
Convert to degrees
34°18' is the same as 34° 18' 0"
34° 18' 0" = 34° + 18'/60 + 0"/3600
= 34.3°
putting tan(34.3) into a calculator in degree mode
tan ( 34°18' )= tan(34.3) = 0.6822
To find the tangent line we will need the slope of the tangent at x=-1 (the x-coordinate of the point given). We find the slope by using the derivative of the curve.
Th curve given is

which can be solved for y by taking the root of both sides. We obtain

We find the derivative using the chain rule. Bring down the exponent, keep the expression in the parenthesis, raise it to 1/2 - 1 and then take the derivative of what is inside.

Next we evaluate this expression for x=-1 and obtain:

So we are looking for a line through (-1,2) with slope equal to -9/2. We use y=mx+b with m=-9/2, x=-1 and y=2 to find b.

2-(9/2)=b
b=-5/2
So the tangent line is given by y=(-9/2)x+(-5/2)
