periodicity of cos(4x)

Solution

periodicity

cos (4 x)

Solution

\frac{π}{2}

Solution steps

Periodicity of

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

Periodicity of

cos (x)

is

2 π

= \frac{2 π}{∣ 4 ∣}

Simplify

= \frac{π}{2}

Popular Examples

domain of sqrt(x^2-7)domain

x^{2} - 7

inverse of ln(x+3)inverse

ln (x + 3)

inverse of (2x-7)/(x+3)inverse

\frac{2 x - 7}{x + 3}

parity f(x)=(5x^2-6x+8)/(6x^7+7x+15)parity

f (x) = \frac{5 x ^{2} - 6 x + 8}{6 x ^{7} + 7 x + 15}

inflection f(x)=xsqrt(400-x^2)inflection points

f (x) = x 400 - x^{2}
