amplitude of-2/7 cos(7/6 x)

amplitude

- \frac{2}{7} cos (\frac{7}{6} x)

0.28571 \dots

Solution steps

f (x) = - \frac{2}{7} cos (\frac{7}{6} x), A = - \frac{2}{7}

Therefore, the amplitude |A| is

0.28571 \dots

0.28571 \dots

sin (2 π t)

f (x) = 3 x - 1

F (x) = x^{3} - 5 x^{2} - 8 x + 4

f (x) = \frac{2 x ^{2} - 3}{x ^{2} - 1}

f (x) = - \frac{6}{x}
