Let $h(x,t)=2+cos(0\mathrm{.}6x-t)$ describe a wave. The value $ofh(x,t)$ gives the depth $of$ the water $incmat$ a distance $x$ meters from $a$

fixed point and $at$ time $t$ seconds. Evaluate $h_x(3,6)$ and $h_t(3,6).$

Round your answers $to$ three decimal places.

$h_x(3,6)=i$

$h_t(3,6)=i$

Interpret $h_x(3,6)$ and $h_t(3,6)in$ terms $of$ the wave.

The value $of{h}_x(3,6)is$

$at$ position $x=3$ and time $t=6.$

The value $of{h}_t(3,6)is$ the

$at$ position $x=3$ and time $t=6.$
