Дано
$$sin{left (a right )} + sin{left (2 a right )} + sin{left (3 a right )} + sin{left (4 a right )}$$
Подстановка условия
$$sin{left (a right )} + sin{left (2 a right )} + sin{left (3 a right )} + sin{left (4 a right )}$$
sin((3)) + sin(2*(3)) + sin(3*(3)) + sin(4*(3))
$$sin{left ((3) right )} + sin{left (2 (3) right )} + sin{left (3 (3) right )} + sin{left (4 (3) right )}$$
sin(3) + sin(2*3) + sin(3*3) + sin(4*3)
$$sin{left (3 cdot 4 right )} + sin{left (2 cdot 3 right )} + sin{left (3 right )} + sin{left (3 cdot 3 right )}$$
sin(3) + sin(6) + sin(9) + sin(12)
$$sin{left (12 right )} + sin{left (6 right )} + sin{left (3 right )} + sin{left (9 right )}$$
