Hi ElectricPavlov,

yes, I know all this, my question really was about the fact that we are now working in 2 quadrants, when we USUALLY work in just one quadrant. I meant to say I did not, and still not really, understand why the question is formulated such that we are to work in 2 quadrants?

Hi guest,

absolutely correct, all of this came to me as well the moment I saw the "hint" from Melody to calculate the volume. I immediately understood things that way. I also explained precisely this to my student, the questions are formulated in this way sometimes, to cause you to think out of the box. Thank you for sharing!

Hi Melody,

The question papers I had belonged to my student, he had in the meantime taken them back to go through them after our classes. so yes, sorry I cannot take a pic of that sum...I will contact him and ask for the papers, hopefully he still has them...I will then send...thank you...

Hi Melody, just busy with math class at moment... Will come back again later... 

Oookay... I can see your angle... I think Ill be able to crack this one... Melody!!... Thank you kindly..
