Code Not Working?

Please contact us if you have difficulty with this process and we'll work it out as quickly as possible. We know how frustrating it is to have an assignment due and be unable to access your textbook.

  • Double-check you placed the correct product into your cart. It should be Differential Equations: A Toolbox for Modeling the World (pdf) for $39. No other product will work with your code.
  • Double-check you typed the code correctly into the Discount code box.
  • If the order completed successfully but you do not see the download link or the email, double-check your spam folder.
  • Be sure you are not using a friend's code. Each code may only be redeemed once. We are a small non-profit trying to lower textbook prices for everyone. Please help our mission by purchasing your own PDF or paperback copy and encouraging your friends to do the same. We appreciate your support.

    I purchased the pdf version of the book. But, inspite of my many mails to the director, I am not able to get the access to the html version of the book. 

    I requested the concerned people to do the needful.
