periodicity of y=cos(5x)

Solution

periodicity

y = cos (5 x)

Solution

\frac{2 π}{5}

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}{∣ 5 ∣}

Simplify

= \frac{2 π}{5}

Popular Examples

f (x) = \frac{1}{3} x^{3} - x^{2} - 8 x + 1

domain of x^2+7 domain

x^{2} + 7

domain of-(31)/((6+t)^2)domain

- \frac{31}{( 6 + t ) ^{2}}

parity y=x^{x^x}parity

y = x^{x^{x}}

intercepts of f(x)=(3x)/(x-4)intercepts

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