Solving Trig Equations using CAS

[Nevil Hopley]

Hello Nspire CAS Handheld users

Attached to this posting is a copy of the recently designed file that supports students who are starting out learning how to solve trigonometric equations.

It follows my recent request on this group for help with troubleshooting one of the manipulation functions that it uses.

Be aware that it is an OS3.0 file and it will not run on OS2.x systems

(I understand that OS 3.0 will be publicly released in the next month, or two)

I therefore also attach a pdf file of its screens for those who are not able to interact with it at this moment in time. 

The last few screen shots in the pdf file show the user defined functions that are embedded in the file. Once these functions are defined, you can delete the page they are on, and you won't delete the function itself.

This will allow you to recreate it on an OS2.x system.

Watch out for the extra decimal points after some of the numbers in the questions - they help prevent fractional terms as you manipulate the equations!

Thanks again to Marc Garneau for his help in troubleshooting the functionality.

Wonderful File!  I just worked through it!  I wish I had had this last week, I just tested on this and it would have been great to teach with this!

 

BTW I am using your idea about the Law of Sines from the internation conference this morning, thanks for the great idea!
