I have a question regarding 11b.

When i read this question i did not know how to answer it as i interpreted it as a completely different cylinder, and therefore thought you cannot make the assumption that the relationship determined in part a (q 11) can be used for any cylinder.

In question 6, shouldn't the vertical translation of the final equation be +5 :S I may be wrong but...
I did dilations first than translations...
