$$cos{left (x right )} = – frac{2}{5}$$
– это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$x = pi n + {acos}{left (- frac{2}{5} right )}$$
$$x = pi n – pi + {acos}{left (- frac{2}{5} right )}$$
Или
$$x = pi n + {acos}{left (- frac{2}{5} right )}$$
$$x = pi n – pi + {acos}{left (- frac{2}{5} right )}$$
, где n – любое целое число
x2 = acos(-2/5)
