I think y=2 there both on the 2 y intercept straight from each Other
The length of each side of octagon is 1.66 inches.
Answer:
3.29
Step-by-step explanation:
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.
