Question

What is the angle between $straight A with rightwards arrow on top plus straight B with rightwards arrow on top space and space straight B with rightwards arrow on top cross times straight A with rightwards arrow on top ?$

Solution

Vector $straight A with rightwards arrow on top cross times straight B with rightwards arrow on top$ is perpendicular to the plane containing $straight A with rightwards arrow on top space and space straight B with rightwards arrow on top.$
$straight A with rightwards arrow on top plus straight B with rightwards arrow on top$ is the resultant of $<pre>uncaught exception: mkdir(): Permission denied (errno: 2) in /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php at line #56mkdir(): Permission denied in file: /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php line 56 #0 [internal function]: _hx_error_handler(2, 'mkdir(): Permis...', '/home/config_ad...', 56, Array) #1 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php(56): mkdir('/home/config_ad...', 493) #2 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/plugin/impl/FolderTreeStorageAndCache.class.php(110): com_wiris_util_sys_Store->mkdirs() #3 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/plugin/impl/RenderImpl.class.php(231): com_wiris_plugin_impl_FolderTreeStorageAndCache->codeDigest('mml=<math xmlns...') #4 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/plugin/impl/TextServiceImpl.class.php(59): com_wiris_plugin_impl_RenderImpl->computeDigest(NULL, Array) #5 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/service.php(19): com_wiris_plugin_impl_TextServiceImpl->service('mathml2accessib...', Array) #6 {main}</pre>$
Therefore the cross product lies in the plane containing $straight A with rightwards arrow on top space and space straight B with rightwards arrow on top.$
∴ Angle between $straight A with rightwards arrow on top cross times straight B with rightwards arrow on top$ and $straight A with rightwards arrow on top plus straight B with rightwards arrow on top$ is $90 degree.$
