A new key to the exact sciences, or, A new and practical theory by which mathematical problems or algebraic equations of almost every description can be solved with accuracy :
and with greater facility and simplicity than they can be by any method that has yet been given by any other author : in which are also introduced, a variety of useful and interesting problems, that have never before been proposed, and which it is believed cannot be solved by any methods or rules except those here laid down /
