MIT Differential Equations

The new MIT Open Courseware Scholar courses are a giant step toward making good instruction available to the wider world. These courses are intended to include all the materials needed for an independent learner, including notes, videos, problems, solutions, and exams. The newest course is Differential equations. Execution is also required, and the first detailed discussion of a DE begins:

Example. Find all solutions to

x” = t

For which they find the general solution

x(t) = t^3/3 + C1*t + C2

Now I have probably forgotten a lot about DE, but that surely doesn’t look right to me.
