Sum

Solution

माना  `I = 1/sqrt((x - 1) (x - 2))  dx`

`= int dx/sqrt(x^2 - 3x + 2)`

`= int dx/sqrt((x^2 - 2 * 3/2 x + 9/4) + 2 - 9/4)`

`= int dx/sqrt((x - 3/2)^2 - 1/4)`

`= int dx/sqrt((x - 3/2)^2 - (1/2)^2)`

`= log abs ((x - 3/2) + sqrt ((x - 3/2)^2 - (1/2)^2)) + C`       `...[∵ int dx/ sqrt(x^2 - a^2) = log |x + sqrt (x^2 - a^2)| + C]`

`= log |(x - 3/2) + sqrt((x - 1) (x - 2))| + C`
