Ahh ok thanks I think I get it now.
So the general formula for a straight line is y=mx+c
are you saying that the derivative of a function gives you the m value needed to plug into the straight line formula?
I'm have trouble understanding a fundamental question of a derivative. So a derivate gives me a tangent line at any given point on a function.
this makes sense for me for a function y=x^2 because the derivative is y'=2x which is a straight line function.
But what about y=x^3 where the...
