This is how to convert from Polar to Rectangular.

There are two formulas to use when converting.

Here are the two formulas to use

• x= r cos(ø)
• y= r sin(ø)

Instead of (x,y) it is (r,ø).

Example 1:

Convert (3,45º) to rectangular.

1. x=3cos45º, so x=1.576
2. y=3sin45º, so y=2.553
3. The rectangular coordinates are (1.576, 2.553)
