Найти производную функции y=f (x) порядка n

y = (1+x^2) * cosx

n=8

1) 2⋅x⋅cos (x) - sin (x) ⋅ (x2 + 1)

2) cos (x) ⋅ (1 - x2) - 4⋅x⋅sin (x)

3) sin (x) ⋅ (x2 - 5) - 6⋅x⋅cos (x)

4) 8⋅x⋅sin (x) + cos (x) ⋅ (x2 - 11)

5) 10⋅x⋅cos (x) + sin (x) ⋅ (19 - x2)

6) cos (x) ⋅ (29 - x2) - 12⋅x⋅sin (x)

7) sin (x) ⋅ (x2 - 41) - 14⋅x⋅cos (x)

8) 16⋅x⋅sin (x) + cos (x) ⋅ (x2 - 55)
