    You're absolutely right that we could use known formulas to calculate the volume. But calculus allows us to find volumes like this even if we don't remember or know the formulas (which is good for me, because I certainly don't remember a formula for volumes of square based pyramids off the top of my head)

    You need more subscribers. Simple videos, clean explanation. Even an idiot doing homework last minute (hello) can understand.

    imperatoreTomas, I'd recommend checking your integration again. Both the integral and your formulas give the same answer, 112/3.

    Thank you SO much! You explained it better than anyone! How would we find the volume of a rectangular based pyramid?

    • @amandadube156
      @amandadube156 9 років тому

      instead of the slice's volume being l^2 dh, it would be l*w dh. Use the same algebraic method to define w as w=wmax(h/hmax), and plug in. In the end, the integral's just more complicated.

    A violin doesn't have a standard function for a base. Standard functions are shapes like triangle, square, and circle. Choose a pop can or something like that and save yourself the headache of trying to graph a violin.

    You weren't supposed to use the height, you were supposed to use the vertical distance along the surface of the triangular face

      @@myaccount6319 yeah, I just started it this semester. And I noticed that you have playlists of CS languages on your channel. I'm currently a math major hoping to get a spot in CS. I'm currently taking courses in CS as well. You should also check out PatrickJMT's channel if you haven't already.
