Hi

Problem 1
How, using Maxima, to solve in elegant way the equation

                 eq:sqrt(x+3-4*sqrt(x-1))+sqrt(x+8-6*sqrt(x-1))=1;

The solution is

                 5<=x<=10

Problem 2

           ex:1/(sqrt((x-b)^2+a^2)*sqrt((x-b)^2/a^2+1));

           integrate(ex,x);

Is the above integral too hard ?
