Limit Formula to Evaluate bŌł½a f ( x)dx

Divide the interval [a , b] into n equal subintervals [ x0, x1 ], [ x1, x2 ], . . . , [ xn-2, xn-1 ], [ xn-1, xn ], such that a = x0 < x1 < x2 < . . . < xn ŌłÆ1 < xn = b . Then, we have x1 ŌĆō x0 = x2 ŌĆō x1 = . . . = xn ŌĆō xn-1 = b-a / n . Put h = bŌłÆa / n. Then, we get xi = a + ih, i = 1, 2, , n.

So, by the definition of definite integral, we get   Tags : Applications of Integration | Mathematics , 12th Maths : UNIT 9 : Applications of Integration
