Ex: Determine the Work Required to Pump Water Out of Trough (Quadratic Cross Section)

This video provides an example of how to determine how much work is required to pump water over the top of a trough that has a cross section of quadratic function.

It has been so damn confusing reading about this, thank you, you explained this very well for me.

Thank you! This really helped me understand the relationship between one section and an integral.

Excellent, thank you!

I was confused because the problem I had said "The vertical cross-section of the trough parallel to an end is shaped like the graph y=x^8 from x=-1 to x=1..." Now, I see they are describing the shape of the bottom of the trough.

may I ask what the situation needs to consider about the acceleration(gravity)?
