Find ye(x) and yt(t). keep in mind that yt(t) should be a trigonometric function of unit amplitude. express your answers in terms of a, k, x, ω (greek letter omega), and t. separate the two functions with a comma.

ye(x) is an envelop it depends only on the positions and yt(t) it depends only on the time. Using the equation1 y(x,t)=A sin(kxâ’ωt) we can find ye(x) and yt(t). Here x value is positive so we can alter that equation1 in positively that is equation2 y(x,t)=Asin(kx+ωt). Let y(x,t)=A sin(kxâ’ωt)=A (sin(kx)cos(ωt)â’cos(kx)sin(ωt)). Sum of equation1 and equation2 then the result is 2A sin(kx),sin(ωt).

The second step on the test was the move he was supposed to
