Page 5: Introduction
Introduction Introduction This document will focus on the Texas Instruments nspire cx CAS calculator. The ability to use a Calculator with a Computer Algebra System is fundamental to be a successful engineering student today. CAS calculators can solve long equations just by typing them in and hitting solve. -

Page 9: Exact And Approximate Results
Results that are not whole numbers will automatically be shown in a fractional or symbolic form. An exact result is a fraction and an approximate result is a decimal. Nspire Example I Trig Functions µ Press to find all the trig functions. TI-nspire CX CAS 2... -
Page 10: Shortcut Keys
Access the list of commands from the catalog. TI-nspire CX CAS 3 Syntax examples appear at the bottom of the screen when scrolling through the list. Press e · to see more examples of syntax. Use the expressions template to avoid syntax errors. -
Page 11: Understanding Variables
Basics Understanding Variables Storing Variables Variables are stored using the define or store commands. Nspire Example II Deleting Variables Delete variables using the Del Var command. Nspire Example III Variable Naming Conventions There are a few ways to name a variable. ... -

Page 15: Symbolic Algebra
Symbolic Math Symbolic Algebra Solving Equations Use the Solve command to save time working out algebra problems. Use this command to solve one equation for one variable or multiple equations for multiple variables simultaneously Nspire Example IV Factoring Expressions Use the Factor command to return an expression factored with respect to a variable. -
Page 16: Understanding Units
When working with units in equations use parentheses to avoid syntax and order of operations errors. Unit Operations To convert units use the Conversion Operator (¢). Nspire Example VII CAUTION: Temperature units must be converted using the Temp Convert command. TI-nspire CX CAS 5... -

Page 27: Programs Make Life Easier
Introduction to Programming Programs Make Life Easier Find a group of problems in a course that use the same equations. Make a flow chart of what to do when you encounter different parameters in this group of problems. Write down the formulas you would need for each step. - Page 28 CAS Calculators Copy the code and test it out. Then try writing a program for a problem in your class. Define LibPub mohr(x,y,τ,β)= Prgm setMode(2,2) setMode(5,2) a:=((y+x)/(2)) r:=√((x-a)^(2)+τ^(2)) setMode(1,6) -y))))/(2)) m:=a+r n:=a-r If α=±45 Then θ:=45 Else θ:=α EndIf φ:=θ+45 t:=r*sin(2*β-2*θ)
