I have no idea whether or not this has been pointed out before, so I'm gonna go ahead and mention it. In the worked example of session 10, at the question (b), there is a mistake in the solution. The function deign solved is f(x)=(x^4+a)/(x^2), whereas the original function was f(x)=(x^4+1)/(x^2). That changes the result, so make sure to keep that in mind, when checking your answer.

The answer to the original problem should be (2x^4-2)/(x^3), instead of (2x^4-2a)/(x^3).
