let 's now generalize what we did in the last video . so if this is my y-axis and this is -- that 's not that straight . this right over here is my x-axis . and let 's say i have two functions . so i 'm just going to say it in general terms . so let 's say i have a function right over here . so let 's say it looks some... | well , over here , once again , we could have defined the interval someplace else , like between there and there . and we would have gotten a different shape . but the points that we care about the way we visualize it is between x is equal to 0 and x is equal to 1 . | how would the volume be calculated if the shape was only partly rotated ? |
