welcome to MSE, could you please be more specific? we may not know the book you are reading. so be particular about asking your problem. –  Une Femme Douce Jan 20 '13 at 17:49
    
The book is "Visual Complex Analysis" by Tristan Needham.....""I am studying on my own."" The problem is " I am finding hard to solve the graphical problems that he asks.. Also please suggest a good software where I can check and plot the equations –  M-a-th-s Jan 20 '13 at 18:02
    
@M-a-th-s What Panu was trying to say is that you should ask specific questions. If you don't know how to solve a particular exercise, type the problem in the question box. –  Git Gud Jan 20 '13 at 18:04

@M-a-th-s Don't type it here, edit the question and type it there. Also edit the title to something like "Sketching a modular surface" or whatever you feel like is a good description of the problem. –  Git Gud Jan 20 '13 at 18:12

1 Answer 1

If I remember correctly from reading Tristan Needham's seminal classic is that he mentions the software he uses as well as the software he recommends to be used in conjunction with the book in the preface.
