Calculus Question - Kurtle - 2011-12-02
For some reason I just can't figure this out, it isn't .5 which is what I keep finding arggg
If

Oops, I meant -0.25. Biased towards your answer.

Shut up and find the mass of a cube of side length a with density function given by f(x, y, z) = sin(x) + e^cox(xy) - z^(3z).

You can always think about something simple like this in terms of area. So for the area under the line y = 2 (for the integration of 2) from 1 to 5 should be 8 units^2, but adding on the integration of 8f(x) results in 6, so the curve 8f(x) from 1 to 5 must have "negative" area under the curve, in this case -2, divide -2 by 8 and you get -0.25

Yeah I figured out how dumb I was, I had to distribute the dx, woops.

Yup, definately -0.25.
