 #### Proportional rescaling
-Each flow is rescaled by a proportional coefficient. The coefficient is defined by $$\alpha_{\text{rescale}} = \frac{max(|AC p1|, |AC p2|)}{|DC p1|}$$.
+Each flow is rescaled by a proportional coefficient. The coefficient is defined by $\alpha_{\text{rescale}} = \frac{max(|AC p1|, |AC p2|)}{|DC p1|}$.
 In this way, the DC flow will have the same magnitude as the AC flow.
 Since we divide by the DC flow to calculate the coefficient, lines with a too small DC flow are not rescaled.
