1. The problem statement, all variables and given/known data for what values of x is cos(x) - sin(x) < cox(x) + sin(x) where 0 =< x =< 2pi 2. Relevant equations none. 3. The attempt at a solution I actually drew out the funtions and added them. In my graphs, I get that: cos(x) - sin(x) < cos(x) + sin(x) for for 0 =< x =< pi When I try to show this in Matlab, i ger messy results? Any ideas?
