2. Find the polar coordinates of 6 radical 3,6 for r > 0.

3. Find the rectangular coordinates of (7, 30°).

4. Write the rectangular equation in polar form.

(x – 4)2 + y2 = 16

5. Write the equation –2x + 6y = 7 in polar form.

6. Find the distance between P1(3, –195°) and P2(–4, –94°) on the polar plane. Round your answer to the nearest thousandth.

7. Write the polar equation in rectangular form.

r = –12 cos(theta)

**Steve**, Tuesday, February 26, 2013 at 4:17amif you know that x^2+y^2=r^2

x=r cosθ

y=r sinθ

all these fall right out.

if you want graphs, visit wolframalpha.com and say

plot r=3-2sinθ

Where do you get stuck on these?
