2*sin(15*cos(a)) если a=1/3 (упростите выражение)

$$2 sin{left (15 cos{left (a right )} right )}$$

$$2 sin{left (15 cos{left (a right )} right )}$$

2*sin(15*cos((1/3)))

$$2 sin{left (15 cos{left ((1/3) right )} right )}$$

2*sin(15*cos(1/3))

$$2 sin{left (15 cos{left (frac{1}{3} right )} right )}$$

2*sin(15*cos(1/3))

$$2 sin{left (15 cos{left (frac{1}{3} right )} right )}$$
