A standing wave results from the sum of two transverse traveling waves given by

y1 = ymcos(kx - ωt)
and
y2 = ymcos(kx + ωt)

where ym = 0.057 m, k = 4.4 rad/m, and ω = 13 rad/s. (a) What is the smallest positive value of x that corresponds to a node? Beginning at t = 0, what is the value of the (b) first, (c) second, and (d) third time the particle at x = 0 has zero velocity?
