Question

ASAP please Find the area of the region R bounded by x- y^2 = 0 x+7y^2 =8

Answer 1

find your boundaries first by setting your functions equal to each other and finding "x"

Answer 2

y= +/- 1

Answer 3

x=1

Answer 4

x = +- 1, too

Answer 5

ok, I am studying this stuff, too; we can do together

Answer 6

sketch the graph first, friend, you do this step, next one will be mine,OK?

Answer 7

so, let you do alone,

Answer 8

i don't know how to graph it on this thing

Answer 9

i've got til 10 to do this problem :/

Answer 10

so, you just need the answer?

Answer 11

before ten, and then i need to work it out for my own sake

Answer 12

ok, I set up the int for you y goes from -1 to 1 , x goes from y^2 to 8 - 7y^2 the function is 1 dxdy you can do it , right?

Answer 13

in two minutes? i doubt it

Answer 14

:(

Answer 15

I think it might be easier if you graphed it as: \(x = y^2\) and \(x =8 -7y^2\) since those are graphs that you can easily graph.

Answer 16

@Hoa are you using greens theorem to evaluate this?

Answer 17

no, hihi... just draw the graph, solve for intersection point, take double integral

Answer 18

what is th greens theorem?

Answer 19

I think you can solve this using single integrals since you're using area "R".

Answer 20

how?show me ,please. I need it for my final
