Definite Integral as the Limit of a Sum
Method of Summation
It is an explanation for finding the integral by the method of summation or by evaluating the integral as limit of a sum (part 3).
Find by the method of summation the value of:
∫ sin xdx, where the lower limit is 0 and the upper limit is (1/2)π,
i.e., integral of sin x, where the lower limit is 0 and the upper limit is (1/2)pi.
