TI-92 application question
I have an interesting situation with my TI-92. It does not seem to correctly
perform Application #5 (the second part - "Finding the Minimum Surface Area
Analytically" on page 349) from the Guidebook. I typed in the example
exactly as indicated. Step 1 returns the desired result, but Step 2 returns
a "Circular Definition" error. What's going on. Also, I tried breaking it
up into two or three separate steps, and eventually got something that could
be simplified into the answer the book gets, although I had to do the
simplifying by hand!
For example, I eventually got y=sqrt(v/x). I tried to solve this for x using
Solve(y=sqrt(v/x),x), and all it returned was the original, y=sqrt(v/x). Why
wouldn't it simplify?
I have ROM 1.11, if that helps.
Thank you,
Darryl Buller
