The period of the cosine function is 2π radians. That is, the value of cos(Θ) repeats every 2π radians. Therefore whatever value of the variable in the function argument causes the argument to change by an amount equal to 2π is the period of the function.
<span>The argument of cos(x/3) is x/3. What value of x makes x/3 = 2π </span>
<span>
x/3 = 2π </span>
<span>
x = 6π
</span>
<span>Therefore the period of y =cos(x/3) is 6π</span>
10+12 is equal to 22. Divide 22 by 2 which is 11. So, the answer to you question is 11.
Hope it helps
