Hi all! i've encountered a problem.As we know the range of 'arcsin' in matlab is -pi/2~pi/2. if we do asin(sin(t)),t= 0:10;we get an wrap answer,but now i want to retrieve the 't',how can i get the original 't'? Thank you!
and we may also encouter such a problem about elliptic integral.For example .elliptic integral of third kind,and it's also period function.My question is how i can get a monotone function.
