periodicity of f(x)=-cos((2x)/5)

Solution

periodicity

f (x) = - cos (\frac{2 x}{5})

Solution

5 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}{\frac{2}{5}}

Simplify

= 5 π

Popular Examples

inverse of f(x)=(x-7)^2+8 inverse

f (x) = (x - 7)^{2} + 8

intercepts of f(x)= 6/7 x-2 intercepts

f (x) = \frac{6}{7} x - 2

simplify (1.6)(0.8)simplify

(1.6) (0.8)

slope of f(x)=10x-5 slope

f (x) = 10 x - 5

range of (-4)/(x^2)+1 range

\frac{- 4}{x ^{2}} + 1
