Matt, If you find it let us know too. The information is usable for newer Casio and Sharp scientific calculator models as well. It is the little brother of your model. Its not like I "needed" another calculator but couldn't pass up a Text Book display calculator for that price.
It's not important. It's a minor compulsion. I can deal with it if I want to. Post: 3. Post: 4. Post: 5. The TI can!
The variable x now has the number that solve arrived at. If you type in the equation and enter it, you get the value of f x at that point.
Nicely, since x root of y is available, answers are available for negative numbers where something like 3 root of x is involved. Post: 6. I tried this earlier and it stayed busy for a while so I didnt think it would work I found these other related undocumented operations the TI36X can do: - Use 2nd Integral in num-solve to solve for uppper, lower limits or even coefficients used in the expression. Post: 7. Funny you should bring that up. Great minds think alike! Post: 8. Don't have the Sharp.
Post: 9. Post: Without having to re type my equation, I can now go to the home screen, hit enter, and f x will come up, evaluated for the x that was calculated for f' x. Your description is quite fascinating.
So I can do this correctly, could you please describe the steps a little more, perhaps a step-by-step example of this? Press table, select choice 2, create your function, clear, press table, choose choice 1 and make f f x. Choose a guess and solve for x. You can then quit, press table, select 1 and enter getting f make that f x , enter and get f x value. Press x, enter, and get the value of x.
I'll try this. The rest of my operations allowed for me to find f x at that value without having to re type the function. Tried it and it worked. Perhaps there's a different method to their madness. I got an EL-WX a few months ago.
Unfortunately, I found what I deem an unacceptably low precision computing a natural log: Correct value to 9 significant figures: ln 0. I cannot remember the source for this test.
