振幅 1/6 cos(7x)

解答

振幅

\frac{1}{6} cos (7 x)

0.16666 \dots

求解步骤

f (x) = \frac{1}{6} cos (7 x), A = \frac{1}{6}

因此，振幅 |A| 为

0.16666 \dots

0.16666 \dots

m o n o t o n e f (x) = \frac{x ^{2}}{2} + \frac{1}{x}

s l o p e 4 x + 6 y = - 5

y = 5^{x}

e x t re m e f (x) = (12 \cdot x^{2} - 60 x + 44)

r an g e f (x) = x^{4} - 29 x^{2} + 100
