The discussion revolves around determining the instantaneous displacement of a sinusoidal sound wave described by a specific wave function. The context involves applying the wave function to find displacement at a given position and time.
Some participants have provided guidance on the calculation process, specifically regarding the mode of the calculator and the conversion of radians to degrees. Multiple interpretations of the calculations are being explored, but there is no explicit consensus on the final displacement value.
There is an emphasis on ensuring the correct mode for calculations and the potential confusion surrounding the conversion of radians and degrees. The original poster questions the correctness of their approach, indicating uncertainty in the process.
s(x,t)=(2.00 μm)cos[(15.7 m^(-1) )x-(858 s^(-1) )t]s (x,t)=(2.00 μm) cos[(15.7 m^(-1) )(0.050m)-(858 s^(-1) )(.003 s) ]
