I was paging merily though my Prescribed book and to my horror I found that my prescribed book has 4 pages missing!

Can anyone perhaps help me out with some copies of p279, p280 and p289, p290 of Willem Labuschagne - "Introduction to Descrete Mathematics for Computer Science"

It would be much appreciated!

Thanks.]]>

Consider (v1 o v2 o v3)(x) = y

v3 would map x to say w, so that (x, w) is an element of V3

v2 would map w to say z, so that (w, z) is an element of V2

v2 would map w to say z, so that (z, y) is an element of V1

Or equivalently

V1(v2(v3(x))) = V1(v2(w)) = V1(z) = y.

My point is that the function on the RHS gets applied first, so it's right to left, not left to right as the question solution seems to suggest.

Also, the solution to the question appears to be inconsistent with the definition of o which is given on page 190 and the theorem on page 202.

I would appreciate a response by one of the lecturers, or a fellow student... Have I missed the plot or is there a genuine faux par in the study guide?

Kind regards,

Richard]]>
