Example for a linear equation: Setup a differential equation for y with

y   t = (exp (-t)) * (sin t)
y'  t = -(exp (-t)) * (sin t) + (exp (-t)) * (cos t)
y'' t = -2 * (exp (-t)) * (cos t)

Thus the differential equation

y'' = -2 * (y' + y)

holds. The following function generates a power series for exp (-t) * sin t by solving the differential equation.
