    #68. it's #67-69. I don't understand the reason for #69, but I know the answer. I know #67 is wrong, but I don't know why, and #68 is the same concept, so I don't know if I did that right either. Thank you!

    For number 69, we can''t integrate that function because it's impossible to make a number of rectangles in a vertical tangent line (You can't have 0 width for a rectangle).
