A wave on a string is described by

D$($x$,$t$)=$D$($x$,$t$)=$

$(2\mathrm{.}00$cm$)$sin$[(12\mathrm{.}57$rad$/$m$)$x$(638$rad$/$s$)$t$](2\mathrm{.}00$cm$)$sin$[(12\mathrm{.}57$rad$/$m$)$x$(638$rad$/$s$)$t$],$

wherexxis inmmandttis inss. The linear density of the string is$5\mathrm{.}00$g$/$m$5\mathrm{.}00$g$/$m$.$

What is the maximum displacement of a point on the string?
