Дано
$$frac{left(sin{left (a right )} + cos{left (a right )}right)^{2}}{sin{left (2 a right )} + 1}$$
Подстановка условия
$$frac{left(sin{left (a right )} + cos{left (a right )}right)^{2}}{sin{left (2 a right )} + 1}$$
(sin((1/2)) + cos((1/2)))^2/(1 + sin(2*(1/2)))
$$frac{left(sin{left ((1/2) right )} + cos{left ((1/2) right )}right)^{2}}{sin{left (2 (1/2) right )} + 1}$$
(sin(1/2) + cos(1/2))^2/(1 + sin(2/2))
$$frac{left(sin{left (frac{1}{2} right )} + cos{left (frac{1}{2} right )}right)^{2}}{sin{left (frac{2}{2} right )} + 1}$$
(cos(1/2) + sin(1/2))^2/(1 + sin(1))
$$frac{left(sin{left (frac{1}{2} right )} + cos{left (frac{1}{2} right )}right)^{2}}{sin{left (1 right )} + 1}$$
