Encyclopedia of Mathematics

Most unusual Encyclopedia. Written by someone who obviously enjoys his work. Lots of interesting math tidbitshistory that I had not seen elsewhere and the Encyclopedia seems thorough.

I am really impressed with this encyclopedia. I am learning about famous mathematicians I've never heard of before. It is brilliant that the encyclopedia covers maths of all different levels right from elementary GCSE level to degree level. I will point out a misprint in this encyclopedia. On page 56 the the algebraic expression (x + 1)(x + 2) / x(x + 1) simplifies to (x + 2) / x or 1 + (2 / x) and not as it says: (x + 2) / (x + 1). Perhaps the publisher might like to make the necessary correction in the database stored on computer so that future copies of this publication show the correct simplification on page 56. I have also noticed a misprint on page 70. In an example of the chain rule for differentiation the derivative of the function: (x^2 + 2)^100 is 200x.(x^2 + 2)^99 and not as it states: 200x.(x^2 + 1)^99. This is probably a typing error since the digit 1 appears instead of 2. Again, this error could be corrected in the database so that the answer to the derivative is correct in later editions of the encyclopedia.
