Solution by Steps
step 1
We start by integrating the function 2xz2x - z with respect to xx from y-y to yy
step 2
The result of the integration is 2yz-2yz, as the integral of 2x2x from y-y to yy is 00 and the integral of z-z is 2yz-2yz
step 3
Next, we integrate the result 2yz-2yz with respect to yy from 11 to zz
step 4
The result of this integration is x(z1)(xz)x(z - 1)(x - z)
step 5
Finally, we integrate the result x(z1)(xz)x(z - 1)(x - z) with respect to zz from 11 to 22
step 6
The final result of the triple integral is (x4z)/2x4/2(x3z2)/2(x3z)/3+(5x3)/6+(5x2z2)/6(5x2z)/6(x^4 z)/2 - x^4/2 - (x^3 z^2)/2 - (x^3 z)/3 + (5 x^3)/6 + (5 x^2 z^2)/6 - (5 x^2 z)/6
[question number] Answer
(x4z)/2x4/2(x3z2)/2(x3z)/3+(5x3)/6+(5x2z2)/6(5x2z)/6(x^4 z)/2 - x^4/2 - (x^3 z^2)/2 - (x^3 z)/3 + (5 x^3)/6 + (5 x^2 z^2)/6 - (5 x^2 z)/6
Key Concept
Triple Integration
Explanation
The triple integral of a function over a given region is evaluated by performing three successive integrations, each with respect to one variable, while considering the limits of integration for each variable.
