Title: graphing inequalities-better on CAS or by hand?
Post by: serendipity21 on May 27, 2013, 09:26:30 pm

hi, so my question is basically explained in the subject haha. When you have a number of inequalities, like 4 or 5, is it better to find the required region by hand or by cas? I sometimes screw up both ways 'cause it gets confusing so I was wondering which is bulletproof for the exam
