Simple, my_notebook ... How steep or shallow the learning curve is when learning a difficult subject. From the previous discussion I would have to say that the 'learning curve' is shallow ... very shallow. Please Register or Log in to view the hidden image!
An excellent case in point. People assume that a shallow learning curve indicates a slow learner, when in fact it means the opposite. Thanks for the props, Chagur. Maybe we can work it out after all. Please Register or Log in to view the hidden image!
"steep learning curve" normally means rapid rise of value in y-axis until it levels off to a straight line parallel to x-axis. Just flip the exponent on the linear axis of the above picture (by Stryderunknown). At least that is what I use the words for.
