FEATURES

    Design features

    The HP40G offers the following design features:

    • 131 x 64 pixel high contrast LCD display

    • 8 line x 22 character display

    • 256 KB of built-in memory

    • 750 functions

    • Built-in Computer Algebra System (CAS)

     

    Statistical inferences

    Statistical inferences include:

    • Testing Hypothesis

    • Measuring confidence intervals that relate to a population

    • Entering, viewing, and editing sample data in table format

    • Plotting results

     

    APLETS (e-lessons)

    APLETS (e-lessons) are a new learning tool from Hewlett-Packard. These electronic lessons are developed from topics in textbooks and then packaged to help students learn math and scientific processes.

     

    Split screen

    The HP40G's split screen offers the option of viewing math relationships in two displays on one screen for side-by-side comparisons.

     

    History of calculations

    The HP40G gives the option of recalling and re-using previously created solutions.

     

    Communications features

    With the unit-to-unit cable that comes with the HP40G, the 40G connects directly to a personal computer, offering the option of sending data, equations, notes, and APLETS (e-lessons) to professors and other students.

     

    Math features

    The math features for the 40g include:

    • Factorization

    The HP 40G’s intelligent editor offers the following options:

    • Evaluate sub expressions

    • Cut, paste, and copy objects

    • Automatically inserts missing parentheses and prompts the next input both in real time

     

    Dynamic algebra and calculus

    Dynamic algebra and calculus features include:

    • Computer Algebra System (CAS)

    • Dynamic symbolic manipulation and symbolic and numeric problem solving

    • Automatically prompts switching to complex mode when working with complex equations or expressions

    • CAS step-by-step mode for dynamic derivation, integration, and linear algebra problem solving (all steps are displayed in textbook mode)
