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 \(\vec{r}\):
say,
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.
