25*(x*sin(x*1/5)*1/5+cos(x*1/5)) если x=-1/3 (упростите выражение)

$$25 left(frac{x}{5} sin{left (frac{x}{5} right )} + cos{left (frac{x}{5} right )}right)$$

$$25 left(frac{x}{5} sin{left (frac{x}{5} right )} + cos{left (frac{x}{5} right )}right)$$

25*(((-1/3)*sin((-1/3)/5))/5 + cos((-1/3)/5))

$$25 left(frac{(-1/3)}{5} sin{left (frac{(-1/3)}{5} right )} + cos{left (frac{(-1/3)}{5} right )}right)$$

25*((-sin(-1/15)/3)/5 + cos(-1/15))

$$25 left(frac{1}{5} left(-1 frac{1}{3} sin{left (- frac{1}{15} right )}right) + cos{left (- frac{1}{15} right )}right)$$

25*cos(1/15) + 5*sin(1/15)/3

$$frac{5}{3} sin{left (frac{1}{15} right )} + 25 cos{left (frac{1}{15} right )}$$

$$5 x sin{left (frac{x}{5} right )} + 25 cos{left (frac{x}{5} right )}$$

25.0*cos(x/5) + 5.0*x*sin(x/5)

$$5 x sin{left (frac{x}{5} right )} + 25 cos{left (frac{x}{5} right )}$$

$$5 left(x sin{left (frac{x}{5} right )} + 5 cos{left (frac{x}{5} right )}right)$$
