WebJan 12, 2016 · So a negative angle is one that starts in a clockwise direction. 60 is the angle 60 degrees above the x-axis so -60 is the angle 60 degrees below the x-axis. Angle measures are considered cyclic and any angle x is equal to x ± 360. So − 60 is the same thing as 300. In particular 180 = -180. Also convenient are -90 = 270. WebSince we are rotating about the y-axis, I believe the y=√x curve is the inner curve and y = x 2 is the outer curve. When I am finding the outer and inner radius do they become negative since I am taking the difference from the the y-axis (x=0)? Right now I have V= ∫ [ π ( x 2) 2 − π ( √ x) 2] d x = − 3 π 10
