Integration as the limit of a sum (III)
Find by the method of summation the value of:
(a) ∫ √x dx (b) ∫ 1/√x dx
Solution: (a) ∫ √x dx Put √x = t , then ½ 1/√x dx = dt or , dx = 2t dt
0 When x = 0 => t = 0
When x = 1 => t = 1
This solution shows how to find the integral by the method of summation of the values in an attached Word file.
