Answer
We can describe the location of a point in the plane using different coordinate systems. The Point P shown in the figure has rectangular coordinates (1,1) and polar coordinates ($\sqrt 2$, $\frac{\pi}{4}$)
Work Step by Step
Look at x and y values of point for rectangular coordinates. To find polar coordinates, remember a polar coordinate is written in the form (r, theta). Using Pythagorean theorem, r = $\sqrt 2$. For theta the arctan of 1 = $\frac{\pi}{4}$
