Fix LinearResistance equation

@@ -22,7 +22,7 @@ A LinearResistance connects two Basins together.
 The flow between the two Basins is determined by a linear relationship, up to an optional maximum flow rate:
 
 $$
-Q_\text{linear_resistance} = \mathrm{clamp}(\frac{h_a - h_b}{R}, -Q_{\max}, Q_{\max})
+Q_\text{linear\_resistance} = \mathrm{clamp}\left(\frac{h_a - h_b}{R}, -Q_{\max}, Q_{\max}\right)
 $$
 
 Here $h_a$ is the water level in the incoming Basin and $h_b$ is the water level in the outgoing Basin.
