Typical Indefinite Integration #2

Calculus Level 5

d x ( x 1 ) 2012 ( x + 1 ) 2014 2013 \Large {\int} \large \frac{dx}{\sqrt[2013]{(x-1)^{2012} (x+1)^{2014}}}

Given that the integral above is defined for x > 1 x > 1 . Ignoring the arbitrary constant, it evaluates to α β ( x λ x + μ ) σ / θ \large{ \frac{ \alpha}{\beta} \left( \frac{x - \lambda}{x + \mu} \right)^{\sigma / \theta }} where α , β , λ , μ , σ , θ \alpha, \beta, \lambda, \mu, \sigma, \theta are positive integers with gcd ( α , β ) = gcd ( σ , θ ) = 1 \gcd(\alpha, \beta) = \gcd(\sigma, \theta ) = 1 . Find the value of α + β + λ + μ + σ + θ + 6033 \alpha+ \beta+ \lambda+ \mu+ \sigma+ \theta + 6033 .


The answer is 10064.

Good. I really don't understand how @Joseph Gomes found the answer 10064 when my problem was set wrong. I hadn't corrected the problem till then.

You can also take (x-1)/(x+1) =t and then integrate
