Easy# Amplitude of a Sine Wave at a Specific Time and Position

WAVES-XF0FL4

A transverse wave on a string is described by:

$$y = 0.62 \sin {(1.75 x – 753 t + 1.047)}$$

…where $y$ is the string displacement in $mm$. What is the displacement of the string at the position $x = 7.20 m$ at a time $t = 8.34 s$?
