Solution 32991: Computing Cross Product on the TI-Nspire™ Family.
How do I compute the cross product of list and vectors on my TI-Nspire family?
The following example demonstrates how to compute the cross product using the TI-Nspire family products.
Example: Find the cross product of lists {5, 5.2, 4} and {2, 6, 3}.
1) Press [home] [A] or add a Calculator App.
2) Press [menu] [7] [C] [2].
3) Press [ctrl] [{}].
4) Press [5] [,] [5] [.] [2] [,] [4] [►].
5) Press [,] [ctrl] [{}].
6) Press [2] [,] [6] [,] [3].
7) Press [enter].
Example: Find the cross product of vectors [2, 2, 3] and [4, 5, 7].
1) Press [menu].
2) Press [7] [C] [2].
3) Press [ctrl] [ [] ].
4) Press [2] [,] [2] [,] [3].
5) Press [►] [,] [ctrl] [ [] ].
6) Press [4] [,] [5] [,] [7].
7) Press [enter].
Please Note: List1 and List2 must have equal dimension, and the dimension must be either 2 or 3. Both Vector1 and Vector2 must be row vectors, or both must be column vectors. Both vectors must have equal dimension, and the dimension must be either 2 or 3.
