How do I enter a vector?
To enter a vector, you may use vector brackets: ❨❩.
To insert vector brackets, you can press Shift+Ctrl+V or Shift+Ctrl+E.
Examples:
u ≔ ❨3, 1, 2❩; v ≔ ❨3, 1, −2❩; u⋅v
6
u × v
⎛−4⎞ e⎜12⎟ ⎝0 ⎠
norm(ans)
12.6491106407 (=4⋅√10)
Hint: To insert the vector product sign, ×, type “\times” or “\cross” followed by space or a punctuation character. In this case, a space will do.
