WebDerivative Of The Dot Product Steps. The derivation is carried out in the following ways, starting with trivial evident facts and ending with the concept of the dot product: … WebIt states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and the hypotenuse c, often called the Pythagorean equation: [1]
