This is what i have so far to find the points that are zero and mark them on the graph. But i cant for the life of me figure out how to proceed. Only started using mathematica last week. I need to mark the min and max values of the function too. But i dont know how to find them.
enter f[x_] = x * Cos[π/6]*(x^5 - 2 x^3 + x) - 0.1;
solution = Solve [f[x] == 0];
zero = Table [{x, 0} /. solution];
Plot [Ekv[x], {x, -1.2, 1.2}, PlotRange -> {-0.12, 0.05},
Epilog -> {Point /@ zero}]
