Some Beautiful Mathematical Formulas




Mathematics is not just about numbers and calculations. It is also about discovering beautiful relationships between seemingly different ideas.

Euler's Identity
e + 1 = 0

Euler's Formula
e = cosθ + i sinθ

Pythagorean Theorem
a² + b² = c²

Quadratic Formula
x = (−b ± √(b² − 4ac)) / 2a

Binomial Theorem
(a + b)n = Σk=0n C(n,k)an−kbk

Geometric Series
1 + r + r² + r³ + ··· = 1/(1−r),   |r| < 1

Area Under a Curve
ab f(x) dx

Fundamental Theorem of Calculus
ab f(x) dx = F(b) − F(a),   where F′(x) = f(x)

De Moivre's Formula
(cosθ + i sinθ)n = cos(nθ) + i sin(nθ)

Fibonacci Sequence
Fn = Fn−1 + Fn−2

Golden Ratio
φ = (1 + √5)/2

These formulas show how mathematics connects algebra, geometry, trigonometry, calculus, complex numbers, and even patterns found in nature.

Mathematics is where simplicity and complexity meet.
