The MTH/VECTOR menu

The MTH menu (

„´

) contains a menu of functions that specifically to

vector objects:

The VECTOR menu contains the following functions (system flag 117 set to

CHOOSE boxes):

Magnitude

The magnitude of a vector, as discussed earlier, can be found with function

ABS. This function is also available from the keyboard (

„Ê

). Examples

of application of function ABS were shown above.

Dot product

Function DOT (option 2 in CHOOSE box above) is used to calculate the dot

product of two vectors of the same length. Some examples of application of

function DOT, using the vectors A, u2, u3, v2, and v3, stored earlier, are

shown next in ALG mode. Attempts to calculate the dot product of two vectors

of different length produce an error message:

1 2 ... 111 112 113 114 115 116 117 118 119 120 121 ... 174 175
