Explanation / Answer

Given that

f(x) = 1/x2 on the interval [ 2 , 5 ] and n = 6

Left end point = 2

Left riemann sum : ( incuding left end point )

( from a to b ) f(x)dx x( f(x0) + f(x1) + f(x2) +...+ f(xn2) + f(xn1) ) , where x = ( ba ) /n.

we have a = 2 , b = 5 , n = 6

x = ( 5 - 2 ) / 6

    x = 3 / 6

  x = 1 / 2

The six subintervals are,

x0 = 2

x1 = 2 + x =    2 + 1 / 2 = 5/2

x2 = x1 + 1 / 2 = 5/2 + 1/2 = 6/2 = 3

x3 = x2 + 1/2 = 3 + 1/2 = 7/2

x4 = x3 + 1/2 = 7/2 + 1/2 = 4

x5 = x4 + 1/2 = 4 + 1/2 = 9/2

f(x) = 1/x2

f(x0) = f(2) = 1/22 = 1/4

f(x1) = f(5/2) = 1/(5/2)2 = 4/25

f(x2) = f(3) = 1/(3)2 = 1/9

f(x3) = f(7/2) = 1/(7/2)2 = 4/49

f(x4) = f( 4) = 1 /(4)2 = 1/16

f(x5) = f( 9/2) = 1/(9/2)2 = 4/81

Hence,

   ( from 2 to 5 ) 1/x2 dx x ( f(x0) + f(x1) + f(x2) +...+ f(xn2) + f(xn1) ) , where x = ( ba ) /n

   1/2 [ (1/4) + ( 4/25) + ( 1/9) + ( 4/49) + (1/16) + (4/81) ]

   0.3573132401

Therefore,

Left reimann sum = 0.36

Right  riemann sum : ( including right end point )

Right end point = 5

( from a to b ) f(x)dx x( f(x1) + f(x2) +...+ f(xn2) + f(xn1) ) , where x = ( ba ) /n.

we have a = 2 , b = 5 , n = 6

x = ( 5 - 2 ) / 6

    x = 3 / 6

  x = 1 / 2

The six subintervals are

x1 = 2 + x =    2 + 1 / 2 = 5/2

x2 = x1 + 1 / 2 = 5/2 + 1/2 = 6/2 = 3

x3 = x2 + 1/2 = 3 + 1/2 = 7/2

x4 = x3 + 1/2 = 7/2 + 1/2 = 4

x5 = x4 + 1/2 = 4 + 1/2 = 9/2

x6 = 5

f(x) = 1/x2

f(x1) = f(5/2) = 1/(5/2)2 = 4/25

f(x2) = f(3) = 1/(3)2 = 1/9

f(x3) = f(7/2) = 1/(7/2)2 = 4/49

f(x4) = f( 4) = 1 /(4)2 = 1/16

f(x5) = f( 9/2) = 1/(9/2)2 = 4/81

f(x6) = f(5) = 1/(5)2 = 1/25

Hence,

   ( from 2 to 5 ) 1/x2 dx x ( f(x1) + f(x2) +...+ f(xn2) + f(xn1) ) , where x = ( ba ) /n

   1/2 [ ( 4/25) + ( 1/9) + ( 4/49) + (1/16) + (4/81) + (1/25) ]

   0.2523132401

Therefore,

Right reimann sum = 0.25
