 The average speed can be calculated by integrating the Maxwell-Boltzmann distribution
 from 0 to infinity and dividing by the total number of molecules. The result is:
-    
+
     .. math:: v_{avg} = \sqrt{\frac{8RT}{\pi M}}
 
 The most probable speed is the speed at which the Maxwell-Boltzmann distribution
 is at its maximum. This can be found by differentiating the Maxwell-Boltzmann
 distribution with respect to :math:`v` and setting the result equal to zero. The result is:
-    
+
     .. math:: v_{mp} = \sqrt{\frac{2RT}{M}}
 
 The root-mean-square speed is another measure of the average speed
 of the molecules in a gas. It is calculated by taking the square root
 of the average of the squares of the speeds of the molecules. The result is:
-    
+
     .. math:: v_{rms} = \sqrt{\frac{3RT}{M}}
 
 Here we have defined functions to calculate the average and
