To do this, we simply reorder the terms of the polynomial in descending order of power.
So, we have:

Answer: it is <CAB
Step-by-step explanation: i just took a test on ed and passed with a 100%
F(x) = cos x
f'(x) = -sin x
f''(x) = -cos x
f'''(x) = sin x
f''''(x) = cos x
90/4 = 22 Remainder 2
Therefore, 90th derivative of f(x) = cos x is -cos x.
