Let                X = 4x and Y = 2x
The general solution for space space cos space straight X space equals space cos space straight Y  is straight X space equals space 2 nπ space plus-or-minus space straight Y comma space straight n space element of space straight Z
rightwards double arrow                        4 straight x space equals space 2 nπ space plus-or-minus space 2 straight x comma space space space straight n space element of space straight Z
rightwards double arrow                        2 straight x space equals space 2 nπ  or space space space 6 straight x space equals space 2 nπ comma space space space space straight n space element of space straight Z
rightwards double arrow                          straight x space equals space nπ        or            straight x equals nπ over 3 comma space straight n space element of space straight Z
Hence, the general solution is: <pre>uncaught exception: <b>mkdir(): Permission denied (errno: 2) in /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php at line #56mkdir(): Permission denied</b><br /><br />in file: /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php line 56<br />#0 [internal function]: _hx_error_handler(2, 'mkdir(): Permis...', '/home/config_ad...', 56, Array)
