Hi all!
I have encountered a problem about 'elliptic integral',I've used 'maple' to calculate
'the third kind incomplete elliptic integral'.I got the outcome that it's something like inverse trigonometric function.So it's a outcome of periodicity,but if i want to change it to monotonous outcome,how can i do ?
It's something like rigid spinning,i want to calculate the angle it rotates and get a monotonous outcome,but actually i get a periodic outcome if i use the elliptic integral.
Actually it's something like the function 'arcsin(sin(theta))',theta is a monotonous variable but finally i get periodic outcome of theta'.How to retrieve 'theta'?
I have calculated this by using matlab but can't get the perfect outcome,if someone has good idea,please email me,and we can discuss the problem together.

Thanks!
sincerely flying
