I thought the same, it's what I assumed (I heard from my teacher) before but I'm not quite sure. By the way, what does "The series must also converge" mean? and I don't know about Differential Galois Theory. Thanx for your reply :smile:
what does an equation need so that the equation can be integrated?
not all of equation can be integarted right?
I was quite confuse if it can be integrated or not whether I found a difficult integration. Thanx
yesterday I had thought it again and I think I have found it. but it's seems diffrent from yours. why does the integration to y? shouldn't it (4-y)? I assumed that the section is under z=4 and above z+y=4 inside x^2+y^2=4.
p=3.14. I will check it again. thanx
oh yes I got it now. you subtract...
find volume bordered by cylinder x^2 + y^2 = 4 and y+z=4 and z=4.
the answer is said to be 16p. but I couldn't find it.
I found it in double integral part.so it must be solved with double integral. I tried with Jacobian tranformation. nut still couldn't solve it. I was confused...
