i have the equation
(http://img16.imageshack.us/my.php?image=71217593.png)
and i want to integrate it from 0 to x
i want to integrate this result again from 0 to x
i used the following code
Qn = 6660 - int('sqrt(1-(x^2)/(16^2))*530','x','0','x')
answer2 = int(Qn,'x','0','x')
and
Q = 6660 - int('sqrt(1-(x^2)/(16^2))*530','x1','x2')
M = 39924 - int(Q,'x','x1','x2')in this case the resul contains x1 and x2 which i replace with x1=0 and x2=16
but the result does not respond to the physics of the problem . So I would really appreciate any ideas of the procedure I should follow .
