Introduction to Programming 27
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. That is basically what a program is.
Make a Simple Program
Mohr’s circle is another problem that is simple but takes longer
than needed to work out. Write a program that solves Mohr’s
circle:
Nspire Example XIV
To make a new program open up the program editor and select
new program and name it Mohr.
