What is Root Finder++?

It's a Library useful to quickly find the Real Roots to a given Equation in a specific Range in two different ways, FUNCTION and POLAR mode. The first one is for function or polynomial type equations like: '3X^2-6X-9' etc… it returns the answer in a real mode. And the Second one is useful for Polar type equations like: '3COS(q )-SIN(5q )' etc... and this one returns an algebraic in polar mode as answer like: '2/3p '.

It is Really Fast, and you can see the number of roots found at the moment, the last Root found and the remaining progress in the screen, and after finding all the Roots in the specified range it uses a Speedy Built-in Browser to show all the Roots Found in the screen, and plus you can send the founded Roots to the Stack for Further Manipulation…

TO INSTALL THE LIBRARY:

Simply download the file named: "ROOTPLUS.LIB" to your HP using binary mode and then on your HP do the following:

To Install the Library Type: 'ROOTPLUS.LIB' RCL 0 STO

To delete the unwanted Var: 'ROOTPLUS.LIB' PURGE

And finally to attach the Library to the home directory, simply turn off your HP, and then on again.

Now you can access the Library's menu label by pressing: [Right-Shift] [2],

then just press the soft key with the label "ROOT", then they will appear three labels: Function, Polar and About.

MAIN FEATURES:

Once you have installed the Library and accessed the Library's menu label like explained above, you will have the next listed functions:

FUNCTION

Executing this label, you will have an Input Form to enter the Equation that you want to scan Roots for, like mentioned earlier, this is for any kind of Equation that you want to get the Roots in real mode. Just enter the Equation and if you want to change the search Range feel free to try with different values.

POLAR

Executing this label, you will also have an Input Form but with different default values, especially designed for Polar type Equations; you will have the same capabilities as in Function mode, but the difference is that you will get the answers in expression form, like ‘11/3p ’.

ABOUT

This is obviously the author’s information screen for the end-user, it only describes the date of making the library…

DELETING THE LIBRARY:

To delete the library in a Very Easy Way, follow the steps:

Just go to the HOME directory by typing HOME and then press [ENTER]

Type :0: 798 and the press [ENTER] twice.
Type DETACH and then press [ENTER].

Finally type PURGE and then press [ENTER], and the Library is finally gone from your HP!!
