periodicity of f(x)=-4cos(x+pi/4)

periodicity

f (x) = - 4 cos (x + \frac{π}{4})

2 π

Solution steps

Periodicity of

a \cdot cos (b x + c) + d = \frac{periodicity of cos ( x )}{∣ b ∣}

Periodicity of

cos (x)

2 π

= \frac{2 π}{∣ 1 ∣}

Simplify

= 2 π

f (x) = 5 + \frac{4}{3} x

f (x) = \frac{x ^{2} - 4}{3 x ^{2}}

cos (sin (tan (5 x)))

f (x) = \frac{8 - 3 x}{x ^{2} - 2 x}

f (x) = - 5 x - 5

What is the periodicity of f(x)=-4cos(x+pi/4) ?
