Hello everyone,
Can anybody help me with my problem -
i require a book on Non Euclidean Geometry which contains both the theoretical part of it and the mathematical (geometrical) part too (e.i sums for practice or for better understanding; like there are many textbooks on algebra or on Euclidean Geometry which contains a number of sums).
Also, if anybody knows about any wonderful book on M-theory as well (too probably with the mathematics being involved, or even only the theoretical explanation) please do tell me.
Thanking you all.
