Note: On the TI-89 Titanium, pressing ¥ s to
display e^( is different from pressing j
On the Voyage 200, pressing 2s to display
e^ is different from accessing the character e
from the QWERTY keyboard.
You can enter a complex number in
form. However, use this form in Radian angle
mode only; it causes a
angle mode.

that an eigenvector is not unique; it may be
