amplitude of cos(θ/4+pi/4)-2

amplitude

cos (\frac{θ}{4} + \frac{π}{4}) - 2

1

Solution steps

Simplify

cos (\frac{θ}{4} + \frac{π}{4}) - 2 : cos (\frac{θ + π}{4}) - 2

f (x) = cos (\frac{θ + π}{4}) - 2, A = 1

Therefore, the amplitude |A| is

1

1

f (x) = x^{2} + 2 x + 1

r (x) = \frac{1}{x - 2}

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

- 4 - 2 cos (5 x)

f (x) = x^{\frac{1}{3}} - 9
