calculus and oranges

Nee was doing advanced calculus tutorial and I menyibuk..

nee: what is 1st octant of a sphere?
me: 1/8 th lo..
*both discussing bout the angles of the spheres..*
me: rotate from 0 to pi over 4 for theta and the same thing for phi...
nee: i want orange! (she was explaining that the angle is wrong)


This is half of an orange

This is quarter

Then, 1/8...


or can cut this way also


So when put on the orange, it is 90 degrees... not 45...

This post is for memory. We ended up eating the orange and still discussing bout it.
I memang don't like calculus wan, but the oranges I like =)
