What is Polar.
Chapter eleven is about polar and nonpolar. In section eleven one we learned conversions of polar to noon polar and vice versa. (x,y) coordinates are nonpolar. R and theta coordinates are polar.
X=rcostheta y=rsintheta
The same formula Is used to convert from polar to rectangular.
R=sqrtx^2+y^2

Give polar coordinates for (3,3)
R=sqrt 3^2=3^2
r=sqrt9+9
r=3sqrt2
tan x=3/3
x=tan-1(1) x=45 from trig chart
(3sqrt2,45 degrees)
