Question

what is euler's formlua?

Answer 1

$\bf\color{magenta}{e^ix=cos \ x+i \ sin \ x}$

e $\bf\color{magenta}{⤳}$Base of the natural logarithm

i $\bf\color{magenta}{⤳}$imaginary unit

x $\bf\color{magenta}{⤳}$angle of radians

$\bf\color{magenta}{---------------}$

It can also written as $\bf\color{magenta}{F+V=E+2}$

$\bf\color{magenta}{---------------}$

$\bf\color{magenta}{More \ to \ know:}$

Euler's identity $\bf\color{magenta}{eiπ+1=0}$

Complex number (exponential form)$\bf\color{magenta}{z =reiθ}$

Complex exponential $\bf\color{magenta}{e x + i y = e x ( cos ⁡\ y + i sin)}$

Answer 2

Answer:

Euler's formula, either of two important mathematical theorems of Leonhard Euler. It is written F+V=E+2, where F is the number of faces,V the number of vertices, and F the number of edges.
