Fundamental Theorems

Pythagorean Theorem

In a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

\( a^2 + b^2 = c^2 \)
Consider a right-angled triangle with sides \(a\), \(b\), and hypotenuse \(c\).
Construct a square with side length \(a + b\).
Arrange four copies of the triangle within the square.
The area of the inner square is \(c^2\).
The total area is also \((a + b)^2 = a^2 + 2ab + b^2\).
Equating and simplifying gives \(a^2 + b^2 = c^2\).

Fundamental Theorem of Calculus

The derivative of an integral of a function is the original function itself. This theorem links the concepts of differentiation and integration.

\( \frac{d}{dx} \int_{a}^{x} f(t) \, dt = f(x) \)
