I can't seem to figure out the following integration:

$\displaystyle

\int_0^1 2\sqrt{1+t^2} dt = \left[2\left(\frac{t}{2}\sqrt{1+t^2} + \frac{1}{2}\ln\left(t+\sqrt{1+t^2}\right)\right)\r ight]_0^1

$

How do i reach the right side of equal sign?

Can anyone kindly tell what method is used for

the above integration?
