Chapter 19 Equation Library The Equation Library is a collection of equations and commands that enable you to solve simple science and engineering problems. The library consists of more than 300 equations grouped into 15 technical subjects containing more than 100 problem titles. Each problem title contains one or more equations that help you solve that type of problem. NOTE: the examples in this chapter assume that the operating mode is RPN and that flag -117 is set. (Flag -117 should be set whenever you use the numeric solver to solve equations in the equations library.) Example: Examine the equation set for Projectile Motion. Step 1: Fix the display to 2 decimal places and then open the Equation Library application. (If #SI# and #UNIT# aren't flagged with small squares, press each of the corresponding menu keys once.)

Chapter 19
Equation Library
The Equation Library is a collection of equations and commands that
enable you to solve simple science and engineering problems. The library
consists of more than 300 equations grouped into 15 technical subjects
containing more than 100 problem titles. Each problem title contains one
or more equations that help you solve that type of problem.
Example
: Examine the equation set for
Projectile Motion
.
NOTE:
the examples in this chapter assume that the operating mode is
RPN and that flag –117 is set. (Flag –117 should be set whenever you
use the numeric solver to solve equations in the equations library.)
Step 1:
Fix the display to 2 decimal places and then open the Equation
Library application. (If
#SI#
and
#UNIT#
aren’t flagged with small
squares, press each of the corresponding menu keys once.)
