Suppose $x$ takes on the values $x=1,1\mathrm{.}2,1\mathrm{.}4,$dots,$5.$ Use MATLAB to compute the array $y$ that results from the function $y=7sin(4x).$ Use MATLAB to determine how many elements are in the array $y$ and the value of the third element in the array $y.$

The number of elements in the array $y$ is

The value of the third element in the array $y$ is $-$
