You get a graph based on polar coordinates rather than Cartesian coordinates. Some shapes have simpler equations in polar coordinates: for example, a circle with centre at the origin and radius r, is simple R = r. A straight line through the origin and gradient (slope) m is tan(q) = m.
use cartesian coordinates
use cartesian coordinates
they both have x and y coordinates
The graph that displays data using line segments is a line graph.
the radius vector; and the vectorial angle the radius vector; and the vectorial angle
The equivalent of the x-axis
a bar graph is a graph that displays data using bars and a line graph is a graph that displays data in a line
A line graph.
Select any value for one of the variables in the graph and solve the equation to get the other variable.
It is the locus of all points whose coordinates satisfy the equation of the line.
When you graph a line using only the slope and a point, you start by graphing the point.
