Hi, 

I am trying to solve 1 equation with goniometric functions so I know the range (0..2*Pi), but it just doesnt solve it (though it solved similar ones before).

fsolve(3.*10^6 = sqrt((-4.2*10^14*(-1.*10^7*u*cos(u) + 3.84*10^8)/((-1.*10^7*u*cos(u) + 3.84*10^8)^2 + 1.*10^14*u^2*sin(u)^2)^(3/2) + 4.2*10^21*u*cos(u)/((-1.*10^7*u*cos(u) + 3.84*10^8)^2 + 1.*10^14*u^2*sin(u)^2)^(3/2))^2 + 7.056*10^43*u^2*sin(u)^2/((-1.*10^7*u*cos(u) + 3.84*10^8)^2 + 1.*10^14*u^2*sin(u)^2)^3), u, u = 0 .. 2*Pi)

Is there some way to get the solution?

Thank you in advance
