I'm in highschool and just started integration. I found the following problem in an old question paper and I find it very challenging.
0 1 x 2 2 x + 1 d x
so I simplified it algebraically to
0 1 ( x 1 ) 2 d x
which of course is
0 1 | x 1 | d x
as the absolute value is a linear function over x [ 0 , ) so I proceed to evaluate it as x 2 / 2 x for upper limit 1 and lower limit 0 which is ( ( 1 ) 2 / 2 1 ) ( 0 0 ) and equals 1 2 , but according to wolfram alpha it is 1 2 .
Please explain at beginner level.
