TI-Nspire – Notes
The Notes application allows you to combine text, formulas, calculations, and chemical notation into a smooth problem-solving flow.
- By default, you type regular text.
- Mathematical content is entered in a Math Box, which you add by pressing CTRL + M.
- If you exit the box using the arrow key, only the formula remains visible.
- If you press ENTER inside the box, the calculation is executed.
- If you press CTRL + ENTER inside the box, an approximate value is calculated.
- Chemical formulas are entered in a Chem Box, which you add by pressing CTRL + E.
- The Chem Box automatically adds subscripts after letters.
- The Chem Box tries to automatically detect capital letters.
- The Chem Box automatically converts the equals sign (=) to a reaction arrow.
On Mac, use CMD instead of CTRL
Dynamic Notes
In addition to taking notes, a nice extra feature is interactivity. When you edit expressions or adjust a slider, the calculation results update automatically.
Exploring limits with a slider
Explore limits dynamically by changing the variable's value with a slider. To get more precise results near the critical point, set a small step size for the slider. You can modify the step size and other settings by right-clicking the slider and selecting 'Settings'.
Taylor approximation and dynamic values
Explore Taylor polynomial approximations by changing the degree with a slider. Set the slider step to 1 (integer) so the degree increases logically. Note that the taylor function calculates the polynomial around the origin (x=0) by default, unless a development center is specified separately.
Binomial expansion with slider
Explore the coefficients and terms of the binomial expansion by changing the exponent (n) with a slider. Set the slider step to 1 (integer) to see how the coefficients from Pascal's triangle are formed for each power.
