Eulers formel, opkaldt efter Leonhard Euler, er en matematisk formel i kompleks analyse, der viser en dyb relation mellem de trigonometriske funktion og den komplekse eksponentialfunktion.. Eulers formel siger at, der for alle reelle tal gælder, at = ⁡ + ⁡ hvor er basen for den naturlige logaritme; er den imaginære enhed.; og er funktionerne sinus og cosinus.

3. P = 21 kW, Q = 16,8 kVAr, S = 26,9 kVA, cos fi = 0,8. Vi fyller i de värden vi känner till i formeln för cosinus: $$\cos v=\frac{närliggande\ katet}{hypotenusa}=\frac{4}{5}$$ För att lösa ut vinkeln v så använder vi den inversa funktionen (arccos): $$v=cos^{-1}\, \left ( \frac{4}{5} \right ) \approx 36,87 ^\circ$$ Alltså vinkeln v, vars cosinus värde är 4/5, är ungefär lika med 36,87 grader. cos Ψ = effektfaktorn (kan avläsas på motorns märkskylt) Effektfaktorn, cos Ψ, bör inte understiga 0,85 för motorstorlekar mindre än 1,5 kW och inte understiga 0,90 för motorstorlekar som är över 1,5 kW.

In 1879, J. J. Sylvester coined the term totient for this function, so it is also referred to as Euler's totient function, the Euler totient, or Euler's totient. Jordan's totient is a generalization of Euler's. The cototient of n is defined as n − φ(n). Substituting r(cos θ + i sin θ) for e ix and equating real and imaginary parts in this formula gives dr / dx = 0 and dθ / dx = 1. Thus, r is a constant, and θ is x + C for some constant C. The initial values r(0) = 1 and θ(0) = 0 come from e 0i = 1, giving r = 1 and θ = x.

It is denoted by the Greek alphabet λ (Lambda). Power factor (λ) = Active power/Apparent power = VI.COS φ/ VI = COS φ The cos phi is a power factor. It is the ratio between active power and apparent power. With alternating voltages, the apparent power S (in VA) of an inductive load is stronger than the active power P (in W) which is actually used by the load. The cos phi equals active power P divided by the apparent power S. cos φ = P/S Examples: Resistive loads: the total power factor in actual is a product of the displacement power factor(cos[fi]) and the distortion power factor.the distortion power factor is a function of the total harmonic distortion,hence the total power factor of the system decreases on in actual practice on account of the presence of harmonics and other non linearities. Thus, it is often called Euler's phi function or simply the phi function. In 1879, J. J. Sylvester coined the term totient for this function, so it is also referred to as Euler's totient function, the Euler totient, or Euler's totient.
