Consider two sinusoidal sine waves traveling along a string, modeled as:

$y_1(x,t)=(0\mathrm{.}45m)sin[(4m^{-1})x+(1\mathrm{.}5s^{-1})t+\frac{}{3}]$ and

$y_2(x,t)=(0\mathrm{.}55m)sin[(12m^{-1})x-(3s^{-1})t].$

What is the height of the resultant wave formed by the interference of the two waves at the position $x=1\mathrm{.}0m$ at time $t=3\mathrm{.}0s?$
