As you very well know, I’m taking Math 1a, Harvard’s Single Variable Calculus class.

The second topic was easy enough, which were functions, something already discussed in pre-calculus classes. Standard, domain, co-domain stuff.

The third topic was interesting. It was about limits, which was what a** function is approaching to as the index approaches a value**. The idea is simple, but I can already imagine the ramifications of such an idea. We look at the **values around** the** ‘answer’**, instead of actually looking at the **‘answer’**, and with the idea of calculus as the **study of change**.

Now perhaps its too early to say this, but I am largely betting on the fact that by solving the homework, we are actually proving a law or something in that sense. The problems are a bit tough, and generally does not only involve the topic being discussed but something more.
