Best ResponseYou've already chosen the best response.0Alright, so I guess it would be best if you learnt how to make a cosine graph and then you will see clearly what exactly the key features are. So this works for both sine and cosine graphs I'll give you some guidelines on how to draw them.

Best ResponseYou've already chosen the best response.0Well I was going to show you how to graph it, but that's exactly right! Depending on the graph assuming we're using dw:1440124411555:dw we should also mentioned the amplitude, if there is a vertical displacement, and a phase shift. But you do have all the essential parts.

Best ResponseYou've already chosen the best response.0i know the amplitude is the distance between the two thingys.. how do i find it?

Best ResponseYou've already chosen the best response.0That's y = cos(x) graph, so the amplitude is the distance from the mid to the max or from the mid to the min. dw:1440124547964:dw

Best ResponseYou've already chosen the best response.0okay! and the displacement is 0 correct?

Best ResponseYou've already chosen the best response.0Phase shift is 0 as well, so it seem you're good!
