Integration as the limit of a sum
Written by :- Thokchom Sarojkumar Sinha
Find the integral by the method of summation the values of :-
b b
(a) ∫ e-x dx (b) ∫ ekx dx
a a
b n-1
Solution :- ∫ e-x dx = Lt h ∑ e-(a + rh) , where nh = b - a
a h→0 r = 0
= Lt h [ e-a + e-(a+h) + e-(a+2h) + ........+ e-{a+(n-1)h}]
h→0
