A wave on a string is described by y$($x$,$t$)=(3\mathrm{.}6$cm$)*$sin$[2$pi$($x$/6\mathrm{.}0$m$)+$t$/(\mathrm{.}016$s$)+1)],$ where x is in m and t is in s$.$ In what direction is this wave traveling? What is the wave speed? What is the frequency? What is the wave number? If the string is under a tension T$=100$N$,$ what is the linear mass density of the string?
