thanks
thanks man I'm working at it, but i don't have any of the course notes at the moment and they havn't been uploaded to the university web space yet
so i don't have any of the formula's handy and i don't know them off by heart
i wouldn't post if i could just look it up, i couldn'd...
hey guys i have two questions that i wouldn't mind some help on !
firstly
a wave in the form (in meters) of y = 0.5sin(4(pi)t+0.5(pi)x) where t and x are time and space co-ordinates in seconds and meters
find the wave length amplitude frequency and speed of the wave.
is the wave...
