Rewrite the integral f (x, y,z) dz dy dx as an iterated integral in the order dx dy dz and dy dz dx x goes from -1 to 1 y goes from x^2 to 1 and z goes from 0 to 1-y for the limits of integration.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
