$6\mathrm{.}13\mathrm{.}1$: Math object. Compute z as the smaller of the sine of x or the cosine of x$.$ Ex: The sine of $1\mathrm{.}5=0\mathrm{.}9974949866,$ and the cosine of $1\mathrm{.}5=0\mathrm{.}0707372016,$ so the smaller value is $0\mathrm{.}0707372016.$ The code outputs the smaller value rounded to five decimal places, so $0\mathrm{.}07074.$
