Hello i need your help with a problem that i can't solve.
I've to find the stationary points of this function y = 3x sin(x) considered bounded between [-2pi:0.01:2pi].
I can't use the command "gradient".. so what shall i do?

I guess it's homework.
They won't let you use gradient, but what about diff?
And failing diff, why not write your own diff?
Or better yet, differentiate analytically and find the roots.
