Hi.   Thanks for the reply.  In performing the integral by hand, one should get upon using the standard Tables of formulae arcosh(9/2*x)+c.  Maple on the other hand gives ln(9*x+sqrt(81*x^2-4)).  I have trouble getting the conversion command to work.  I wonder why Maple fails in this case?!   Maybe someone knows how to make it work?  Some Maplesoft technie perhaps?  :)

Hi gkokovidis.  Thanks for that. 

I have got the beautiful plot. :)   However, how do I get the actual equation (x+5)^2 + y^2 >= 16 through Maple though from the inequality? 

Thanks.

Hi Robert.  First of all, thanks for your reply.  There are some information missing in your reply.  Can you please tell me what goes after "gridrefine=3, fill"? 

Many thanks.  :)
