    Graduate J.J Thomson's determination of of the ratio m/e

    find \SigmaFx \SigmaFy in terms of E,H,e etc. \SigmaFx = md2x/dt2 \SigmaFy = md2y/dt2 and solve the differential equations.

    Undergrad Solving ODE: $\frac{dx}{dt}=ax(b-x)$

    dx/(ax(b-x)) = dx/abx + dx/ab(b-x) = dx/abx - d(b-x)/ab(b-x) and then you can integrate these terms.
