I just finished answering a thread on graphing and I realized that I am lacking in that area as well.
I'm sure I should know this stuff already, but I don't. So I know how to graph trig and exponential functions when they are shifted and things like that, but how do you graph them when you have a combination? For instance, let's say I wanted to graph:
y = e^(2x) + e^(5x) ...to keep it simple
so i can graph e^2x and e^5x, piece of cake, but graphing their sum, I don't know.
or how about products:
e^x * sinx
or e^x * sinx + e^(3x)cosx
or sin(x + 2)*cos(x - 3)
I was also curious about the applications of graphs in biology, when they talk about "steady state solutions" and their graphs, but i guess i'll leave that for another thread another time.
