For example if then relationship to sin and cos in euler s formula if we replace θ with θ in euler s formula we get.

Euler s formulas math. Euler s formula named after leonhard euler is a mathematical formula in complex analysis that establishes the fundamental relationship between the trigonometric functions and the complex exponential function euler s formula states that for any real number x. The first is a topological invariance see topology relating the number of faces vertices and edges of any polyhedron. A cube for example has 6 faces 8 vertices and 12 edges and satisfies this formula. Where e is the base of the natural logarithm i is the imaginary unit and cos and sin are the trigonometric functions.

It is written f v e 2 where f is the number of faces v the number of vertices and e the number of edges. Euler s formula is a relationship between exponents of imaginary numbers and the trigonometric functions. See how these are obtained from the maclaurin series of cos x sin x and eˣ.
