Tutored by
A little about me: I'm about the biggest Indie fan there is, I almost exclusively watch (John Hughes>>) 80s movies or the upcoming Star Wars series, and I read sci-fi in my spare time. I tutor for the sake of those aha moments, and have taken Multivariable Calc, Linear Algebra, Real Analysis, and Complex Analysis. Who knows what I'll tutor next, hope to see you soon.

Proofs, proofs, proofs!
Today we'll be getting to one of my favorite parts of this unit, proving the Sum Rule, Power Rule, Product Rule, and Quotient Rule--all different techniques which allow us to differentiate functions! That should take us around an hour or so, so we'll use the remaining hour to practice these new and *extremely important techniques.

(Session time: 1h30m)
To wrap up the second half of our proofs section of this second unit, we'll spend the first 20 minutes of today's session practicing some of the rules which we learnt yesterday, and then go on to derive the derivatives of sin(x), cos(x), tan(x), csc(x), sec(x), cot(x), ln(x), e^x, a^x, and log_a(x)! We'll probably spend another 30 minutes practicing applying these. Don't worry if that doesn't seem like enough--we'll spend the rest of the series practicing these!

Today we'll be practicing all the differentiation rules we've learnt so far, first through some practice problems and then by completing the Unit Test together for the "Differentiation: definition and basic derivative rules" unit.

Now that we've learnt all the basic theory, we can apply our knowledge of derivatives by dealing with
-Second derivatives

Now that we've gone over all the "rules" regarding derivatives, as well as some of the common applications of derivatives, we can focus on the principal role derivatives play: allowing us to find the minimum and maximum of functions. In order to do that, though, we must first come up with some really important results:
-L'Hôpital's rule and the special case of L'Hôpital's rule
-The Mean Value Theorem for derivatives
-The Extreme Value Theorem
-Rolle's Theorem
We'll prove L'Hôpital's rule and its special case, and the proof of the other three will be provided in writing.

In single-variable calculus, there are two ways of finding the extrema of functions...today we're learning the second way:
-Introduction to concavity
-The Second Derivative Test
-Points of inflection
If we have enough time, we'll take on
-challenging AoPS optimization problems,
which essentially constitutes some practice of how calculus is actually used in real life: maximizing the profit of your company given limited resources or some other constraint, etc.
(Sneak peak: the technique most often employed in order to deal with optimization problems in multivariable functions is called the method of Lagrange multipliers in case you're interested in finding out more about it).
