Calculate [3,4]x5
Calculate [-2,4]÷2
Absolute value of the vector
The absolute value function “ABS”, when applied to a vector, produces the
magnitude of the vector. For a vector A=(A1, A2, …An), the magnitude is defined
as = .
1. Press
2. Enter a vector
3. Press
For example: Absolute value of vector [5,12]:
3
.The answer is 13. In RPN mode:
