Hey guys, i have the solution manual for my calc book but this problem set is really stumping me. I look at the examples, i look at the solution, i look at the steps but can't seem to see exactly what they're doing. Can anyone help?! Use analytic methods to find the extreme values of the function on the interval and where they occur. f(x) = sin (x + (pi/4)) , 0 <= x <= (7pi/4) I know it's probably an easy problem and i don't really need to know the solution. I'm just having a really difficult time figuring out exactly what to do for problems like these. ANYONE care to explain? Thanks!
