Finding optimal value for x

I want to find the optimal (x) value:

While having possible minimum value for >> 2.4*cos(x)

And possible maximum value for >> (35.4/1.7(sin(x))2+(cos(x))2)+274.5

Please give me some hints on what function/algorithm I should start with.

Appreciate any help

You could try this function to get numeric values for local minimums:

Or you could take the derivative, set it = 0, and solve for x.
