Vector calculation
Use VECTOR
mode to perform calculation with vectors.
Open the mode dialog by pressing MODE button, then select VECTOR
to enter VECTOR mode.

The VECTOR menus
Pressing SHIFT 5 will open the VECTOR
menu

There are 3 tabs:
The NAMES menu
The NAMES
tab contains 4 vector variables: VctA
, VctB
, VctC
and VctD
. Selecting an item in NAMES
tab will insert the vector variable to the calculator screen.

The EDIT menu
The EDIT
tab contains 4 items: VctA
, VctB
, VctC
and VctD
. Selecting an item will open the vector editing screen.

The MATH menu
The MATH
tab contains operator and functions that operation on vectors. There are some builtin functions:
Dot
: computes the vector dot productAngle(vectorA, vectorB)
: Return angle between two vectorsNormalize(vector)
: Calculates the normalized vector (or unit vector)Cross(vector1, vector2)
: Cross productProjection(vector, vector2)
: Find the orthogonal projection of vector1 onto another vector2

-
(Optional) Change the vector dimension by pressing the Change dimension button. Select R2 or R3.
-
Enter vector values
Example:
VctA = (4,-5)
-
Press AC to back to calculation screen
