I've cut the question in half because the other parts require graphing.

The answer to those questions specifically is "There aren't any"
Judging from your reply, you didn't post the right domain

 

[SpiralFlex]

Sorry, I didn't see that error, fixed now.

 

[hscishard]

Cool
Now the question isn't that interesting anymore lol (to hsc students)

Correct.

you might get more than 50% hsc mark for 2unit with that performance ( if you are very lucky )

I did full working on paper and typed in the end-result solutions on here. I don't do full-working on here, dickhead. And if you need to see full-working for such a simple question I would suggest it is you who would struggle in the test, not me.

Going to keep this thread going. Next question was taken from James Ruse 1997 paper.

Question 5: The area bounded by and is rotated one revolution about the x axis. Find the exact value of the volume of the solid formed.

May I remind members to stick to the thread topic. Insulting others will not be tolerated. If you have an issue with another member sort it outside these forums.
