Given:


\begin{gathered} \text{ For cos equation Amplitude : 6, period : }2\pi,\text{ vertical shift : 0, and } \\ \text{ horizontal shift : }(2\pi)/(3). \end{gathered}

Required:

Find the cos equation.

Step-by-step explanation:

First of all we need to know cosine function. That is


\begin{gathered} y=Acos(B\theta-C)+D \\ Where, \\ A(Amplitude) \\ (2\pi)/(|B|)=period \\ (C)/(B)=phase(horixontal\text{ s}hift) \\ D=vertical\text{ }shift \end{gathered}

Now, the equation


y=6cos(\theta-(2\pi)/(3))
