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

The MATH tab contains operator and functions that operation on vectors. There are some builtin functions:

Dot: computes the vector dot product
Angle(vectorA, vectorB): Return angle between two vectors
Normalize(vector): Calculates the normalized vector (or unit vector)
Cross(vector1, vector2): Cross product
Projection(vector, vector2): Find the orthogonal projection of vector1 onto another vector2

Editing Vector Variable Value

Open the EDIT menu
Select a vector variable item
(Optional) Change the vector dimension by pressing the Change dimension button. Select R2 or R3.
Enter vector values

Example: VctA = (4,-5)
