Homework Statement
A wave on a string is described by the following equation: y = (15cm)cos(πx/5.0cm - πt/12s). Sketch this wave from x = 0 to x = 10 cm for the t = 0.
The Attempt at a Solution
Honestly, I've never seen this notation before. I have no idea how to interpret it. I tried googling some help and now I'm more confused. I tried setting t to 0 and putting different values for x in order to get a value for y, but I get 14.9... for every value of x, which gives me a straight line, and that answer was incorrect. It might be hard to explain this online, but I would appreciate it immensely if somebody would please try. I'm utterly lost.
