I figure if I can make an expression for x and y at various points I can get the slope of the line L, which is the value of the derivative. |dw:1326841893689:dw|The figure lets me get L-x for the horizontal side of the triangle, but what is the height?I don't know if I'm headed in the right direction, since what I called P is a function of x...
But if I could get two coordinate values I suppose I could make a formula for the slope of the line L, which would be f'(x)
Toughie...
