Question

Accepted Answer

$y=0.2\sin \,\left[ 2\pi \left( 6t-\frac{x}{60} \right) \right]$

Answer

$y=0.2\sin \,\left[ 2\pi \left( 6t+\frac{x}{60} \right) \right]$

Answer

$y=0.2\sin \,\left[ \pi \left( 6t+\frac{x}{60} \right) \right]$

Answer

$y=0.2\sin \,\left[ \pi \left( 6t-\frac{x}{60} \right) \right]$
