    Integration as the limit of a sum (II)

    Written by :- Thokchom Sarojkumar Sinha

    Find by the method of summation the value of:-

    (1/2)π b
    (a) ∫ sin x dx (b) ∫ cos θ dθ
    0 a

    (1/2)π n-1
    Solution :- (a) ∫ sin x dx = Lt h ∑ sin (rh) , where nh = (1/2)π - 0 = (1/2)π
    0 ...
