Vectors
This Chapter provides examples of entering and operating with vectors, both
mathematical vectors of many elements, as well as physical vectors of 2 and 3
components.
Entering vectors
In the calculator, vectors are represented by a sequence of numbers enclosed
between brackets, and typically entered as row vectors. The brackets are
generated in the calculator by the keystroke combination „Ô ,
associated with the * key. The following are examples of vectors in the
calculator:
[3.5, 2.2, -1.3, 5.6, 2.3] A general row vector
[1.5,-2.2] A 2-D vector
[3,-1,2] A 3-D vector
['t','t^2','SIN(t)'] A vector of algebraics
Typing vectors in the stack
With the calculator in ALG mode, a vector is typed into the stack by opening
a set of brackets („Ô) and typing the components or elements of the
vector separated by commas (‚í). The screen shots below show the
entering of a numerical vector followed by an algebraic vector. The figure to
the left shows the algebraic vector before pressing `. The figure to the right
shows the calculator’s screen after entering the algebraic vector:
In RPN mode, you can enter a vector in the stack by opening a set of brackets
and typing the vector components or elements separated by either commas
