Tips for using TI-nspire

Basic calculations

Degrees and radians

When calculating with angles, you can use degrees or radians. In Math AI SL course radians are not required, so I recommend you to set both settings to degrees.

In all other IB courses (Math AI HL, Math AA SL and Math AA HL) you must know how to calculate in degrees and in radians.
You can select degrees for both: calculations and graphs, but this is not recommended.
It's possible to select degrees for calculations and radians for graphs, but this is not recommended either.
I recommend you to select radians for both: calculations and graphs. When radians are selected, you will still be able to calculate with degrees (and minutes and seconds) if you use the ° ' '' symbols. Enter the angle using ° ' '' symbols and the calculator will convert the angle to radians automatically.
Calculation   \(\sin(30^\circ)\)  returns the result   0.5.
Calculation   \(30^\circ+60^\circ\)   returns the result   1.5708,  which is the correct result in radians. You can convert it to degrees using the command   Ans►DD  ("Decimal Degrees") or   Ans►DMS  ("Degrees-Minutes-Seconds").

Solving equations

You can use the following functions to solve simple equations and systems of simultaneous equations.

Graphs

Warning: Some of the functions described here are not available in the scratchpad mode. You must open a document with graphs page to use them.

Derivatives and integrals

Binomial distribution and normal distribution

TI-nspire has several built-in function to calculate probabilities connected with the binomial and normal distribution: binomPdf, binomCdf, normCdf, etc. You can use these functions in three different ways:

Page Sorter

Page Sorter is a special program which will help you organize documents with multiple pages. It shows all pages (as icons) on the same screen and then you can select what to do with them.
