સંબંધ અને વિધેય

સંબંધ S = {(x + y) । x, y

element of

N, x + y = 8}નો પ્રદેશ અને વિસ્તાર શોધો.

x + y = 8 માટે, $bold y bold space bold less-than or slanted equal to bold space bold 7$

$open parentheses bold because bold space bold x bold space bold element of bold space bold N bold space bold ત ે થ ી bold space bold y bold space bold equals bold space bold 8 bold space bold rightwards double arrow bold space bold x bold space bold equals bold space bold 0 bold space bold not an element of bold space bold N bold space bold space bold therefore bold space bold y bold space bold not equal to bold space bold 8 close parentheses$

yની શક્ય કિંમતો 1, 2, 3, 4, 5, 6, 7 છે.

હવે, yની આ કિંમતો માટે xની સંગત કિંમતો 7, 6, 5, 4, 3, 2, 1 થાય.

આમ, S = {(7,1), (6, 2), (5, 3), (4, 4), (3, 5), (2, 6), (1, 7) }

આથી Sનો પ્રદેશ = {1, 2, 3, 4, 5, 6, 7}

અને Sનો વિસ્તાર = {1, 2, 3, 4, 5, 6, 7}

A = {1, 2, 3, 5}, B = {4, 6, 9}, સંબંધ S = {(x, y) । x અને yનો તફાવત અયુગ્મ સંખ્યા છે ; $<pre>uncaught exception: Http Error #404 in file: /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/plugin/impl/HttpImpl.class.php line 61 #0 [internal function]: com_wiris_plugin_impl_HttpImpl_0(Object(com_wiris_plugin_impl_HttpImpl), NULL, 'http://www.wiri...', 'Http Error #404') #1 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/php/Boot.class.php(769): call_user_func_array('com_wiris_plugi...', Array) #2 [internal function]: _hx_lambda->execute('Http Error #404') #3 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/haxe/Http.class.php(532): call_user_func_array(Array, Array) #4 [internal function]: haxe_Http_5(true, Object(com_wiris_plugin_impl_HttpImpl), Object(com_wiris_plugin_impl_HttpImpl), Array, Object(haxe_io_BytesOutput), true, 'Http Error #404') #5 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/php/Boot.class.php(769): call_user_func_array('haxe_Http_5', Array) #6 [internal function]: _hx_lambda->execute('Http Error #404') #7 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/plugin/impl/HttpImpl.class.php(27): call_user_func_array(Array, Array) #8 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/haxe/Http.class.php(444): com_wiris_plugin_impl_HttpImpl->onError('Http Error #404') #9 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/haxe/Http.class.php(458): haxe_Http->customRequest(true, Object(haxe_io_BytesOutput), NULL, NULL) #10 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/plugin/impl/HttpImpl.class.php(40): haxe_Http->request(true) #11 /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/plugin/impl/TextServiceImpl.class.php(80): com_wiris_plugin_impl_HttpImpl->request(true) #12 /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) #13 {main}</pre>$ } આપેલો છે.
