Eksempler
<math> \operatorname{erfc}(x) = \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt = \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}} </math>
<math> x = \sqrt{ 200 } </math>
- Effekt
<math>P = U \cdot I = {U^2 \over R} = R \cdot I^2</math> | (1) |
- leger og tester på Michaels side
<math>U = R \cdot I</math>
- tja
<math>3X = Y \Rightarrow X = {Y \over 3}</math>
