The final part of the second question on Unit 3.3 appears to be wrong.
From one student on the course:
the solutions for 3.3 question 2 say that N has to be at least 323 to get the error below 0.01 for the forward and backward difference. If I try N=323 I still get an error of 0.99, and to get below 0.01 i need N=33000! My errors otherwise are exactly the same as in the table...
I can reproduce this, so need to double check all those numbers presented there.
Also, the formatting is slightly off for that second question.
