Calculator Tips

This page contains information about how to use various calculators for different classes.

Dot and Cross Products

Vectors may be entered surrounded by { }. That is, for some vector \(\vec{r}\):

\( \begin{align} \vec{r}&=r_x\hat{\imath}+r_y\hat{\jmath}+r_z\hat{k} \end{align} \)

say,

\( \begin{align} \vec{r}&=3\hat{\imath}-2\hat{\jmath}+6\hat{k} \end{align} \)

the TI version of the vector would be:

{3, -2, 6}

Be sure to use the unary negative operator (-) versus the binary subtraction operator - at the start of negative entries.
