Para hallar los extremos hay que resolver la ecuación
$$\frac{d}{d x} f{\left(x \right)} = 0$$
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
$$\frac{d}{d x} f{\left(x \right)} = $$
primera derivada$$e^{\sin{\left(2 x \right)}} \cos{\left(2 x \right)} - \sin{\left(2 x \right)} = 0$$
