periodicity of f(x)=cos^2(x/(1800))

periodicity

f (x) = cos^{2} (\frac{x}{1800})

1800 π

Solution steps

Periodicity of

cos^{n} (x) = \frac{Periodicity of cos ( x )}{2},

if n is even

Periodicity of

cos (\frac{x}{1800}) : 3600 π

= \frac{3600 π}{2}

Simplify

= 1800 π

y = (1 + x)^{2}

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

f (x) = 40 x^{2} - 69 x - 6

f (13) = 16 x^{2} + 72 x + 81

f (h) = h^{742} - 70
