The problem is F(x) = x + cosx
Find intervals where the function is Increasing
I took the first derivative and I'm lost as to where to go. Any help?
F'(x)= 1 - Sinx

Set the first derivative equal to zero. the values you get for x will be your critical points. Then, test those critical points on a number line by plugging a number on either side of each critical number to test. If the answer is negative, it is decreasing. If the answer is positive, it is increasing. Use that to figure out max and min if you need. hope that helped. =]
