Entering Points | Syntax
Cartesian
To plot a set of points (x, y), for example,
{(1, 2), (π, 2), (sin(1.3), 1)}
type in
1, 2; pi, 2; sin(1.3), 1
That is, enter the ordered pairs without paranthses, and separate them with ;.
Polar
To plot a set of points (θ, r), for example,
{(2.3, 3), (π, sin(2))}
type in
2.3, 3; pi, sin(2)
That is, enter the ordered pairs without paranthses, and separate them with ;.
Note: You can use any numeric (constant) expression such as 1.5+2e+log(10)/2 for the components of a point.
Pressing the Draw Graph button repetitively connects the points with straight lines or labels them.
To draw a (closed) polygon enter the vertices and re-enter the first vertex after the last vertex.
