if 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?
1.Graph the polar equation r=3-2sin(theta)
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)

I'm taking this same class you should add me on Facebook lol Symone kaepernick
Identify the conic section whose equation is r=6/(2-3 cos theta).
