What is the volume of the solid produced by revolving #f(x)=abssinx-abscosx, x in [pi/8,pi/3] #around the x-axis?
I supplied the missing the factor 1.2 in the integral of sin 2x now. I
am sorry for missing it, in my earlier version..
Both sin x and cos x are > 0 in (0,
Now, the volume of solid of revolution is
we observe a maximum deviation of
Attached a plot with
The difference between the computed volumes using either function is in the order of
