Today we learned about Polar Coordinates. Basically, this is another form of graphing other than using the x and y axis. In particular, this graph uses circles and radians to graph plot points. Here is some vocabulary commonly used in polar coordinates.
r = directed distance from O to P
Theta = directed angle, counterclockwise from polar axis to segment OP.
In addition, there are coordinate conversions you need to know in order to be able to understand your points.
Polar to Rectangular Conversion
During a Polar to Rectangular Conversion, you will be given points (r, theta) and you will plug them into the corresponding coordinate conversion equation. (x = cos, y = sin)
