Simon Bridge said:The notation does not seem to make any sense in this context.
The only thing I can think of is:
$$\int_0^1 dx \int_0^{x^2} dy \int_0^y dz \frac{z}{1+x^2}$$
Simon Bridge said:"area of integration"?
Suggests the limits are not as right as they look - maybe vanhhees is on to something?
Perhaps you should tell us what the integral is supposed to find?
Are you trying to find a volume?

A triple integral is a mathematical tool used to calculate the volume under a three-dimensional surface. It is similar to a regular integral, which calculates the area under a curve, but the triple integral takes into account three dimensions (x, y, and z) instead of just two.
In this specific problem, the bounds are 0 <= z <= y <= x^2 <= 1. This means that the integral is being calculated over a region where z is between 0 and 1, y is between 0 and x^2, and x is between 0 and 1. This can be visualized as a three-dimensional shape with these boundaries.
To solve a triple integral, you need to first determine the bounds and the function being integrated. Then, you need to set up the integral using the appropriate notation (either Cartesian, cylindrical, or spherical coordinates). Finally, you can use various techniques such as change of variables or symmetry to simplify the integral and solve it using standard integration methods.
Yes, triple integrals can be solved using different coordinate systems such as Cartesian, cylindrical, and spherical coordinates. The choice of coordinate system often depends on the given boundaries and the complexity of the function being integrated.
You can check your solution by using a computer program or calculator to evaluate the integral. You can also use visualization tools to plot the three-dimensional shape and see if your calculated volume matches the actual shape. Additionally, you can compare your solution to a known solution or ask a colleague or instructor to review your work.
