• What are the Limits of integration? So Interval Notation?

• Kav10
+1

The limits of integration are written in the seventh line. 2 and (3-sqrt(5))/2.

• Kav10
+1

Does that make sense?

• But they should be this intervals of region A and B so: Region A: From -2 to -1 Region B: From -1 to 0.6 (which is the square root used)

• No, when integral is dy, the interval should be from y axis, when it is dx, the interval should be from x axis. See the solution where it uses the y limits for the integral …dy and x limits for integral …dx. Does that make sense now?

• Yes, so you used Horizontal slices

• Both. Yes.
