A caluclus work problem.
A cylindrical tank of radius 4 ft and length 12 ft is lying on its side on horizontal ground. The tank initially is full of gasoline weighing 40 lb/ft3. How much work is done in pumping all this...

A plane region is bounded by the Graph of the equation y=3-x^2 and y=abs(x). Finding the volume of by rotating the region about the x-axis.
normally I would know hoe to solve this is a number was in the place of the x but since the x is there, I'm stuck.
prove that three collinear points can determine a plane.
Find dy/dx by implicit differentiation for y cos x = 1 + sin(xy)
