can someone answer what is double integral?

Question

anonymous · Answer

The multiple integral is a type of definite integral extended to functions of more than one real variable, for example, f(x, y) or f(x, y, z). Integrals of a function of two variables over a region in R2 are called double integrals.

its an iterated integration ....

@amistre64 the integral of an integral?

amistre64 · Answer

in a sense ... yes :)

amistre64 · Answer

but usually its assignment is for multivariables

dmezzullo · Answer

never really understood calc 1.

anonymous · Answer

tototot is my another account. so, how do you find a double integral?

amistre64 · Answer

essentially it goes something like this
$$\int_{p}^{q}\int_{a}^{b}f(x,y)~dy\ dx$$
$$\int_{p}^{q}\left(\int_{a}^{b}f(x,y)~dy\right)\ dx$$
$$\int_{p}^{q}\left(F(x,b)-F(x,a)\right)\ dx$$
$$\int_{p}^{q}g(x)\ dx$$
$$G(p)-G(q)$$

amistre64 · Answer

lol, got my p and q backwards

dmezzullo · Answer

that is pretty much what I think of as an integral of an integral.

amistre64 · Answer

the notion is valid, but im sure there are sticklers that would frown on that assessment

anonymous · Answer

how do you find a double integral?

amistre64 · Answer

an integral can find an area under a curve; so say an integral of an integral amount to saying the area of the area under a curve.

double integration is finding the volume under a surface ....

amistre64 · Answer

I just showed you the basic steps .... unless youve got something specific to toss around its the best we can do
