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 split screen offers the option of viewing math relationships in
two displays on one screen for side-by-side comparisons.
History of calculations
The calculator gives the option of recalling and re-using previously
created solutions.
Communications features
With the unit-to-unit cable that comes in the package, the calculator
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 calculator include:
Factorization
Expansion
Substitution
Systems of linear equations
Linear algebra
Matrices
Trigonometry (trig. and hyperbolic functions, degrees, and radians)
