The HP 38G provides built-in applications to solve specific
kinds of math problems. These little applications, or aplets,
are accessed from the Library (| lib |).
The library lists (and manages) all the aplets in the
calculator, whether they came with the calculator or were
added later.
There are six types of math aplets built into the HP 38G :
• Real-valued, rectangular function y in terms of x. Example:
y = 2 x - e 3.
• Parametric functions x and y in terms of t. Example: x =
cos(0 and y = sin(f).
• Polar function r in terms of an angle 8.
Example: r = 2cos(40 ).
