Kcalculating The Outer Product Of Two Vectors; Kdetermining The Absolute Value Of A Vector - Casio fx-570MS User Manual

k Calculating the Outer Product of
Two Vectors
Use the procedure described below to obtain the outer
product for two vectors.
• Example: To calculate the outer product of Vector A and
Vector B
(VctA VctB)
• An error occurs in the above procedure if you specify
vectors of different dimensions.
k Determining the Absolute Value of
a Vector
Use the procedure shown below to obtain the absolute
value (size) of a vector.
• Example: To determine the absolute value of Vector C
(AbsVctC)
• Example: To determine the size of the angle (angle unit:
Deg) formed by vectors A = (–1 0 1) and B = (1 2 0), and
the size 1 vector perpendicular to both A and B.
