" * Plot graphs with greater precision than competing calculators.

* Plus, the HP 39gII offers a programming language that’s modern and complete with user-defined variables and functions.

* This graphing calculator is loaded with 15 applications to help students learn. For example, manipulate a graph and see the associated equation change instantly using the HP explorer app.

* The HP 39gII boasts more than 600 built-in functions, powerful HP solvers and unit conversions."

Outline
Exploration, study and imagination mathematics and science ideal tool
HP 39gII graph calculator's being published is helps the student to explore, the study and in the visualization mathematics scientific field essential concept. This ideal classroom graph calculator may carry on the preservation to your operation, later may also share together with other people. Uses the commonly used algebra data feeds, explains each kind of question likely on the paper using the mark, the digit and the graph view enhancement solves the problem and studies the interactive historic record to be possible to review and processes the data to explore and in the study with ease founds and uses the apps application program counter's user interface and the built-in help support Chinese and English.

Formidable function
1. the built-in application library of subroutines, the scientific constant and the part help you to solve the complex problem. Through to mark, digit and graph
2. the exploratory development produces to a complex mathematics concept better understanding.
3. using mathematics science in physical constant and huge unit conversion built-in library of subroutines.
4. splendid performance and sufficient memory
5. easy to read display monitor.
6. the utilization formidable HP solution and the application procedure solve the difficult problem.

Highly effective design
1. the math student's necessity, may preserve your operation, later comes back also to be possible to share together with other people.
2. presses down a button then to carry on the cut in the view.
3. the use slipper type apron strengthens the protection.
4. in the emergency case only need use the single-node battery.

Visits the HP resources and the online tool
You may also obtain and download under HP supports and strengthens the high quality online tool, such as solutions and the study and so on course, educational resources opportunity obtains from yours calculator are more.
