| Case 1: exy > 0 and ex > ey |
| The principal axes are counterclockwise to the current axes (because
exy > 0) and no more
than 45º away (because ex
> ey).

| Case 2: exy < 0 and ex > ey |
| The principal axes are clockwise to the current axes (because exy < 0) and no more than
45º away (because ex >
ey).

| Case 3: exy > 0 and ex < ey |
| The principal axes are counterclockwise to the current axes (because
exy > 0) and between
45º and 90º away (because ex < ey).

| Case 4: exy < 0 and ex < ey |
| The principal axes are clockwise to the current axes (because exy < 0) and between 45º and
90º away (because ex <
ey).

|
| Case 5: exy = 0 and ex > ey |
| The principal axes are aligned with the current
axes (because ex >
ey and exy = 0).
![]() |
|
|
| Case 6: exy = 0 and ex < ey |
| The principal axes are exactly 90° from the
current axes (because ex
< ey and exy = 0).
