 A region described by inequalities in cylindrical coordinates 2015-02-21 Rahul pose la question :I am not able to visualize a solid given by inequalities as under (in cylindrical coordinate system) 0= I know that (can visualize) first 2 inequalities say it is a cylinder of infinite length. It seems that third inequality poses the restriction to the height as well as it makes us to remove a cone. But I just can not understand it clearly. Thanks in advance! Regards, RahulPenny Nom lui répond.
