So, because the tangent line is a good approximation of the cost function, the derivative of C â called the marginal cost â is the approximate increase in cost of producing one more item. Marginal revenue and marginal profit work the same way.ay that you have a cost function that gives you the total cost, C (x), of producing x items (shown in the figure below). The derivative of C (x) at the point of tangency gives you the slope of the tangent line.
