Skills against Beer

This is a quick look at how my general skills evolve with my consumption of alcohol (in amount of beers). Notice the descending part of the function has a slope equal at about 1.5 times the ascending part, but fortunately declining as my skills approach zero (skills cannot be negative and the graph would need a longer x-axis to see the function touch 0).

Social Life vs Finals

Social life plotted against time. I can't wait to see the effect of the asymptote.

Maximize Coffee Enjoyment

Knowing my "Enjoyment of Coffee" function, which depend on temperature (T) and the temperature of coffee function, I've been able to determine when to drink my coffee to enjoy it at utmost. It would need further description to know the exact time when to drink and when not to drink, but this gives a good idea of the problem.

Edit: I should correct a mistake: the "drink" portion of the curve should go a little further at the end of the chart, as I'll start enjoying my coffee before its temperature becomes optimal, then enlarging the timelapse I should drink my coffee. Also, the temperature function of time shouldn't be a straight line, as it will eventually stagnate at room temperature.
