Yesterday I sent the two differential equations to you by e-mail. But there was an error in the initial conditions. The initial conditions are taken at r=5.67. I didn't plug this value into the equation. After plugging in this value, the correct initial conditions are:
x(5.67) = - {a[5.67*b + (32*b^2 + a^2 + 0.0019)^(1/2)]}/(a^2 + 0.0019)

y(5.67) = -{0.043*[5.67*b + (32*b^2 + a^2 + 0.0019)^(1/2)]}/(a^2 + 0.0019)

while the two differential equations are the same. I am sorry about this.
