Just to reassure you – the proof that power series can be differentiated term by term inside their radius of convergence is listed in our notes as being “non-examinable”, though I suppose that might not have been the case in 2003.

Hello,
there is a minor typo, in the inductive step. “The first term is equal to …” should evaluate the derivative at 0, not t, and the integral just above this line should have dx, not dt.

I hope you keep up this series of exam questions – it’s extremely insightful, though I’m a little surprised at how much energy is devoted to second guessing the examiner’s intentions.

Cheers

Thanks — corrected now.

Dear Mr. Gowers,

I really enjoy your writings, and I hope to see many more of them in the future!

However, I’d like bring to your attention the fact that the math formulas (images of a rather poor quality, if I may say so) are almost unreadable when printed on paper. I’m not sure if you are aware of this (or if you care about it), but I thought I’d mention it just in case.

I’m not very technical and I’m sorry that I cannot provide you with a solution or be of any help otherwise. Perhaps the people at WordPress can help you.

Best Regards,
Paul Weemaes
