The value of $∫\frac{dx}{x^2-6x+13}$ is : |
$\frac{1}{2}tan^{-1}\frac{x-3}{2}+C, $ where C is constant of integration. $\frac{1}{2}cot^{-1}\frac{x-3}{2}+C, $ where C is constant of integration. $\frac{1}{2}tan^{-1}\frac{x+3}{2}+C, $ where C is constant of integration. $\frac{1}{2}cot^{-1}\frac{x+3}{2}+C, $ where C is constant of integration. |
$\frac{1}{2}tan^{-1}\frac{x-3}{2}+C, $ where C is constant of integration. |
The correct answer is Option (1) → $\frac{1}{2}\tan^{-1}\frac{x-3}{2}+C, $ where C is constant of integration. $∫\frac{dx}{x^2-6x+13}$ $=∫\frac{dx}{(x-3)^2+2^2}$ $=\frac{1}{2}\tan^{-1}\frac{(x+3)}{2}+C$ |
