They look great! Good job

2. That_one_guy16

Nice

3. coolaidd

Sorry, I know its alot :/

4. Dido525

Lol :P .

7. Dido525

The rest of it looks fine.

8. Dido525

I CANNOT help you on the polar coordinates though as I have not learnt them.

9. coolaidd

ok how do i figure out 25?

10. Dido525

Ohh it's 5^0 ! I thought it said 9 :P .

11. Dido525

Then you are correct ^_^ .

12. coolaidd

ok...soo everything else (besides polar coordinates) are correct??

13. Dido525

Yep :) . To me.

14. coolaidd

thank you soooooo much! :)

15. Dido525

You are welcome! :) .

16. Ledah

Don't you feel confident enough with your answers?

17. Ledah

seems like you've answered them to the best of your ability.

18. coolaidd

Yes.. but its not about just being confident..I want to be correct

19. Dido525

Aren't you going to submit it? :P .

@Dido525 question 14 looks correct for the graph of 1+3i http://assets.openstudy.com/updates/attachments/50ca22a9e4b0a14e43695095-coolaidd-1355424646452-screenshot20121213at1.40.18pm.png

The other would be (-2, 3+2sqrt(2)) http://assets.openstudy.com/updates/attachments/50ca22a9e4b0a14e43695095-coolaidd-1355424828452-screenshot20121213at1.45.38pm.png 24, asks for the minor axis vertices, and you've given the major axis vertices. Minor axis vertices should be (-3, 3) and (-1,3) http://assets.openstudy.com/updates/attachments/50ca22a9e4b0a14e43695095-coolaidd-1355424827838-screenshot20121213at1.45.51pm.png 27 should be ln12/ln5, how'd you get ln5/ln10?
