periodicity of y=3cos(2x)

Solution

periodicity

y = 3 cos (2 x)

Solution

π

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}{∣ 2 ∣}

Simplify

= π

Popular Examples

inverse of f(x)=7x+3 inverse

f (x) = 7 x + 3

domain of f(x)=log_{2}(1-|1-x|)domain

f (x) = lo g_{2} (1 - ∣ 1 - x ∣)

asymptotes of f(x)=(1+2x^2)/(5x+3x^2)asymptotes

f (x) = \frac{1 + 2 x ^{2}}{5 x + 3 x ^{2}}

domain of (1-7x)/9 domain

\frac{1 - 7 x}{9}

intercepts of f(x)=2x^2+3x-3 intercepts

f (x) = 2 x^{2} + 3 x - 3
