What is the period of y = 8 cos (5pie x + 3pie/2)-9<br> Give an exact value. Units

zzz [600]

$\\ \rm\Rrightarrow y=Acos(Bx+C)+D$

This is the general formula and the period is 2π/B

Now our given function

$\\ \rm\Rrightarrow y=8cos\left(5\pi x+\dfrac{3\pi}{2}\right)-9$

On comparing we get

A=8
B=5π
C=3π/2
D=-9

Period:-

$\\ \rm\Rrightarrow \dfrac{2\pi}{B}$

$\\ \rm\Rrightarrow \dfrac{2\pi}{5\pi}$

$\\ \rm\Rrightarrow \dfrac{2}{5}$
