# Thread: Sketches of polar curves

1. ## Sketches of polar curves

Hellow everyone. Well Ive gt some Hmwrk on polar curve sketching and I've done them. BuT in the book I used there's on answer about them. I'm studying a Distance Education MAths MOdule. Can anyone help me or sugest a software that can display these graphs for me to checK...

well here are the equations:

1. r=4sec [theta]

2. r=3sin[theta]

3. r=3cosec[theta]

4. r[square]=a[square]sin 2[theta]

5. r[square]sin 2[theta]=c[square]

I'll be very glad if someone could really help.. Thanks in advance...

this software can graph polar curves. it is very user friendly. if you have any questions on how to use it, say so

Okay, I'm stumped. How can you make this do polar graphs?

click on "function" in the top menu bar, go to "insert function." at the very top of the dialogue box, there is a drop down menu titled "type of function." in this menu, there is an option for polar functions

Let me just take this opportunity to say

Doh!

Thanks!
