Read the following information and answer the three items that follow.
Consider the function
f(x) = g(x) + h(x)
where, g(x) = sin$$\left( {{x \over 4}} \right)$$
and h(x) = cos$$\left( {{{4x} \over 5}} \right)$$
Consider the function
f(x) = g(x) + h(x)
where, g(x) = sin$$\left( {{x \over 4}} \right)$$
and h(x) = cos$$\left( {{{4x} \over 5}} \right)$$
What is the period of the function g(x)?
