![screenshot of problem text: Click this link to go to a Desmos graph of a function f(x). Part of the point of this is to increase you
familiarity with Desmos and to leverage it to do something interesting.
Use this for help using lists in Desmos: https://bit.ly/3fE0uMC Note that if I have a list L = [1,4,3] defining
M = 2·L will define M to be [2,8,6]. If I have two lists, for example L & M and I have Desmos plot (L,M) it
will plot the following ordered pairs: {(L1, M1), (L2, M2), (L3, 3)} = {(1,2), (4,3), (3,6)}
Use function notation and your knowledge of difference quotients draw estimated tangent lines at regular
points along the graph of the function. I say estimated because we can’t let h = 0 lest we ask Desmos to
divide by zero. Instead, we’ll let h be a very small number, say h = 0.001.
The end result should look something like this. Use the + icon to add a note and include your name & date.
Save your graph as PCalc PS-02 Number 6 and submit the link to me on the Problem Set #2 assignment on
Google Classroom.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:jnf4fqcqqrshcl5ef6qfxa5h/bafkreibvqduot36zoeq26plutwno7tcxsjdwcc3dwq2m75cibmlxnhd3by@jpeg)

The answer is always some sort of floating point nonsense

You know the TV trope where there's an angel & devil on your shoulder trying to convince you to act as they would like? This is what I feel like having bought a stuff capybara sort of for myself ("I'll have my partner give it to me for xmas") but knowing I should probably give it to my niece

I'm not the one teaching it for the first time (just a quick refresher) but I try to mention how the change of variables means we're kind of swapping a "hard integrand" and an "simple path" for a "simpler integrand" and different path such that the areas as the same
