    Let M_1 = first midpoint.

    Let M_2 = second midpoint

    I need to show that M_1 = M_2.

    M_1 = [(a + b)/2, (c + 0)/2)]

    M_1 = [(a+b)/2, c/2)]

    M_2 = [(a + b + 0)/2, (c + 0)/2]

    M_2 = [(a + b)/2, c/2)]

    So, M_1 = M_2.

    I will begin to post Calculus 1 questions on limits this weekend, Lord willing. Look for calculus questions in the Calculus Forum.
