    Find the Riemann sum

    Here is my example
    To estimate the area under the graphof f(x) = 2/x + 6 from x=2 tro x=6
    Find the Riemann sum usiing right endpoints and n = 4.
    R4 = ?
    Find the Riemann sum using left endpoints and n= 4.
    L4 = ?

    Thank You,
    Keith

    Let x_0=2,x_1=3,x_2=4,x_3=5,x_4=6
    Then
    R_4=\sum_{i=1}^4f(x_i)(x_i-x_{i-1})

    L_4=\sum_{i=1}^4f(x_{i-1})(x_i-x_{i-1})
