Converting Coordinates from Polar to Rectangular
Key Questions
-
Answer:
All Polar
rarr Rectangular coordinate conversions are based on the definitions ofsin andcos :
color(white)("XXX")sin(theta)=y/rcolor(white)("XXX")cos(theta)=x/r Explanation:
There may be many ways to visualize the conversion of Polar to Rectangular coordinates. Sometimes (depending upon the values of
r ortheta ) it is easier or faster to see this conversion graphically or in some other form, but in the end it comes back to the relationship betweenx, y, r, and theta as defined by the trigonometric functions.
(I assume here that we are dealing only with Real values ofx, y, r, and theta ). -

Polar coordinates to rectangular conversion :
y = r sin theta, x = r cos theta
