Find the equation of the normal to the curve f(x) = 3cos(2x) at the point x = 0.

In class, we learnt to find the derivate of the function, which would represent the slope.

After I did that, I found the slope to be 0.. but that is not what my graphing calculator tells me.. So, I'm not too sure where I went wrong :S
