I think I just broke my TI-83 calculator!
Ok,
So like when I try to graph something like cos3x, which should turn out to be a wavy-like graph, instead, I get just a linear line for y=x. Help please!
THanks

Change the mode from degrees to radians.
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
