Chapter 11

We learned some pretty basic stuff this past week.
Today, we are going to learn how to convert from Polar to Rectangular.
It is easy to do it the other way too, but we're going to save that for next week :)
To convert from polar to rectangular, you need to know two fomulars.

These formulas are:
  • x= r cos(ø)
  • y= r sin(ø)
In the chapter, instead of using (x,y), you will be using (r,ø) in place of it.

Now for the example:
Convert (2,30º) to rectangular.
  1. The first thing you need to know is that 2 is your r and 30º is your ø.
  2. x=2cos30º, so x=sqrt 3
  3. y=2sin30º, so y=1
  4. Your rectangular coordinates is (sqrt 3, 1)
AND THAT IS HOW YOU CONVERT FROM POLAR TO RECTANGULAR :)
CARLEYYYYY(:
