is beta/m broken?

m_list = []
for slope_in_radians in slope_in_radians_list:
    beta = ((numpy.sin(slope_in_radians) / 0.0896) /
            (3 * numpy.sin(slope_in_radians)**0.8 + 0.56))
    m_list.append(beta/(1+beta))
    beta_list.append(beta)
matplotlib.pyplot.plot(slope_in_radians_list, beta_list)
matplotlib.pyplot.plot(slope_in_radians_list, m_list)
matplotlib.pyplot.show()
