I just wanted to point out a fact obvious to most of you, the fact that:

CALCULUS IS AWESOME!

I pity people who are introduced to in a gentle step by step fashion, making it all seems natural and obvious. It's much more fun when you find it totally confusing and then finally BAM! the light dawns.

But don't expect too much from calculus. It's power in a vast number of situations can mislead you into thinking it can tackle anything. When it comes to things like finding computer algorithms to interpret pictures or decrypt codes, its capability is less impressive. Maybe we've yet to invent the best math for things like that.

This. Calculus is a sledgehammer. Sure you can open a walnut with a sledgehammer, but do you want to?

I'm pretty sure you've seen the "fence by the river problem": you have a length of wood P long and you need to build a rectangular fence with one side the river bank. A student using calculus would set up the equations

##A = xy##

##P = 2x + y##

then solve the second equation for y, then substitute into the first equation, then differentiate and find the stationary point, find y, and finally prove that you have a max. It'll take at least half a page.

Or you can just use the AM-GM inequality

##A = xy = \frac{1}{2} \sqrt{2xy}^2 \leq \frac{1}{2} \left(\frac{2x+y}{2}\right)^2 = \frac{P^2}{8}##

with equality when ##2x=y## and the problem is solved. Just because calculus can tackle a lot of different problems does not mean it is always the best tool for the job.

I'm glad it plays such an integral role in your life.

Ah, our first derivative joke.

Would anyone like to make a second derivative joke?

Depends on the school, but if you've taken all 3 semesters, you should be fine. Maybe linear algebra would help (LA always helps).

Definitely Liebniz. All of Newton's work was rather *puts on sunglasses* derivative.

Yes it's Leibniz. My google doesn't even want to search 'Liebniz' and tells it searches for 'Leibniz' instead. But the observation is how often in English ei and ie are confused, while no German or Dutch will ever make that mistake.

Pronounce it like l-eye-b-niths, not leabniths

We do, it's called Linear Algebra!
