The directions state to find any critical numbers of the function within the interval 0 < x < 2pi. The function is:
[tex]h(x) = sin^2(x) + cos(x)[/tex]
I've already found that the derivative is:
[tex]2sin(x)cos(x) - sin(x)[/tex]
I've set that equal to zero, and that's where I'm stuck. I guess this is more of an algebra question than anything. The answer I keep getting is:
[tex]tan(x)/sin(x) = 2[/tex]
However, I don't think its correct. So any help would be greatly appreciated.
