periodicity of f(x)=cos(2x-pi/2)

Solution

periodicity

f (x) = cos (2 x - \frac{π}{2})

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

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

f (x) = 2 x + 3

inverse of f(x)=(3x+2)/(2x-1)inverse

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

parallel x+4y=-2 parallel

x + 4 y = - 2

inflection f(x)=\sqrt[3]{1-x}inflection points

inverse of f(x)= 1/3 x-9 inverse

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