sin(a) cos(a) (tan(a) + cot(a))
Упрощаем:
(sin(a) cos(a)) (tan(a) + cot(a))
sin(a) * cos(a) is the same as 1/2sin(2a), using the double angle identity.
(1/2sin(2a)) * (tan(a) + cot(a))
Now, simplify the expression:
(1/2sin(2a)) (tan(a) + cot(a))= 1/2 sin(2a) (tan(a) + cot(a))= 1/2 (2sin(a)cos(a)) (tan(a) + cot(a))= sin(a)cos(a) (tan(a) + cot(a))= sin(a) cos(a) (tan(a) + cot(a))
Таким образом, упрощенное выражение: sin(a)cos(a)(tan(a) + cot(a)).
sin(a) cos(a) (tan(a) + cot(a))
Упрощаем:
sin(a) cos(a) (tan(a) + cot(a))
(sin(a) cos(a)) (tan(a) + cot(a))
sin(a) * cos(a) is the same as 1/2sin(2a), using the double angle identity.
(1/2sin(2a)) * (tan(a) + cot(a))
Now, simplify the expression:
(1/2sin(2a)) (tan(a) + cot(a))
= 1/2 sin(2a) (tan(a) + cot(a))
= 1/2 (2sin(a)cos(a)) (tan(a) + cot(a))
= sin(a)cos(a) (tan(a) + cot(a))
= sin(a) cos(a) (tan(a) + cot(a))
Таким образом, упрощенное выражение: sin(a)cos(a)(tan(a) + cot(a)).
