Question

Solve Volume using Double integral: region bounded by z=4y and z=x^2+2y^2

Answer 1

?thanks?

Answer 2

wrong thing obviously haha

Answer 3

convert the boundaries to polar coordinate

Answer 4

equal the Z1=Z2 and find your boundries and use cosx for x and sinx for y

Answer 5

ehh it that always the systematic way of doing it? or no and this is the chapter before polar... so i was trying to do without it

Answer 6

okay

Answer 7

so you are guys still not in the polar coordinate yet

Answer 8

cause the intersection will create the disk on the xy plane.. we have gone over polars just it's before the chapter

Answer 9

set Z1=Z2 and you will find the x=is going to be x=square root of (2y^2-4y) and your Y=(0,4)

Answer 10

but what is the function you are integrating

Answer 11

are you okay
