Polar and Cartesian Coordinates

This calculator handles the following conversions:

* Ordered Pair Evaluation and symmetric points

* Polar coordinates of (r,θ°) to Cartesian coordinates of (x,y)

* Cartesian coordinates of (x,y) to Polar coordinates of (r,θ°)

* Quadrant (I,II,III,IV) for the point entered.

* Equivalent Coordinates of a polar coordinate

* Rotate point 90°, 180°, or 270°

* reflect point over the x-axis

* reflect point over the y-axis

* reflect point over the origin

Relative Coordinates

Given a starting point (x_{1},y_{1}), this will determine your relative coordinates after moving up, down, left, and right.

Triangle Coordinate Items

Enter 3 points for the vertices of a triangle, and this will calculate the area of that triangle and the centroid.

Unit Circle

Determines if coordinates for a unit circle are valid, or calculates a variable for unit circle coordinates
