(adsbygoogle = window.adsbygoogle || []).push({}); 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?
