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
