Step-by-step explanation:
To solve this without L'Hopital's rule, multiply by the conjugate, (1 − cos n + sin n) / (1 − cos n + sin n).
The numerator becomes:
(1 − cos n + sin n) (1 − cos n + sin n)
(1 − cos n + sin n) − cos n (1 − cos n + sin n) + sin n (1 − cos n + sin n)
1 − cos n + sin n − cos n + cos² n − sin n cos n + sin n − sin n cos n + sin² n
2 − 2 cos n + 2 sin n − 2 sin n cos n
2 − 2 cos n + sin n (2 − 2 cos n)
(1 + sin n) (2 − 2 cos n)
The denominator becomes:
(1 − cos n − sin n) (1 − cos n + sin n)
(1 − cos n)² − sin² n
1 − 2 cos n + cos² n − sin² n
1 − 2 cos n + cos² n − 1 + cos² n
2 cos² n − 2 cos n
-cos n (2 − 2 cos n)
Dividing, the 2 − 2 cos n factors cancel out, leaving us with:
(1 + sin n) / -cos n
The limit as n approaches 0 is therefore:
(1 + 0) / -1
-1

Step-by-step explanation:
CMF is easy though.
There are no negative signs. so A and B is excluded
Divide the x+5 in the trinomial so u can get the CMF of the equation
