Manny's Weekly Rant (Ep. 1)

[r]When you’re finding the particular solution to a nonhomogeneous equation and you get an unknown constant (which is all/most of the time), you don’t use the solution equation of the whole differential equation as a basis for finding that unknown constant! You have to substitute the particular solution with the unknown constants into the original differential in order to find that constant. ARGH!!!

There goes 3 well deserved points.
