Дано
$$frac{sin{left (2 a right )} + sin{left (6 a right )}}{sin{left (6 a right )} + cos{left (2 a right )}}$$
Подстановка условия
$$frac{sin{left (2 a right )} + sin{left (6 a right )}}{sin{left (6 a right )} + cos{left (2 a right )}}$$
(sin(2*(-3/2)) + sin(6*(-3/2)))/(cos(2*(-3/2)) + sin(6*(-3/2)))
$$frac{sin{left (2 (-3/2) right )} + sin{left (6 (-3/2) right )}}{sin{left (6 (-3/2) right )} + cos{left (2 (-3/2) right )}}$$
(sin(2*(-3)/2) + sin(6*(-3)/2))/(cos(2*(-3)/2) + sin(6*(-3)/2))
$$frac{sin{left (frac{-18}{2} right )} + sin{left (frac{-6}{2} right )}}{cos{left (frac{-6}{2} right )} + sin{left (frac{-18}{2} right )}}$$
(-sin(3) – sin(9))/(-sin(9) + cos(3))
$$frac{- sin{left (9 right )} – sin{left (3 right )}}{cos{left (3 right )} – sin{left (9 right )}}$$
Численный ответ
(sin(2*a) + sin(6*a))/(cos(2*a) + sin(6*a))
Соберем выражение
$$frac{sin{left (2 a right )}}{sin{left (6 a right )} + cos{left (2 a right )}} + frac{sin{left (6 a right )}}{sin{left (6 a right )} + cos{left (2 a right )}}$$
