Unchained Melody

Last night's mathematics for economists lecture and quiz gave me a rude awakening that I had to study in order to excel at this class. Last week's ninety minute lectures spoiled me into thinking that this would be a cake course and I'd arrive home by 8pm. Yesterday's lecture comprised of basic calculus, especially the chain rule, and differentiation. Later this afternoon, I will read some the material so that I would not be further behind.
