 Polar Coordinates and Equations

 

    1. Plot each point given in polar coordinates.    SOLUTION

     (a) (4,3π4)              (b)  (3,π6)               (c) (2,π2)   

    2. Which quadrant does the the following point lie in?    SOLUTION

     (a)  (r,θ)=(1,7π6)          (b)     (r,θ)=(2,5π6) 

          

   3. Perform each indicated conversion. Answer using exact values.   SOLUTION

     (a) Convert (x,y)=(2,2) to polar coordinates (r,θ) such that r>0 and 0θ<2π.

     (b) Convert (r,θ)=(3,3π4) to rectangular coordinates (x,y).

    4. Perform each indicated conversion. Answer using exact values.     SOLUTION

    (a) Convert (x,y)=(0,7) to polar coordinates (r,θ) such that r>0 and 0θ<2π.

    (b) Convert (r,θ)=(3,5π6) to rectangular coordinates (x,y).
