Let’s fingerpaint a bit, and get into the chemistry along the way. The natural log can be seen as an integral, or the time needed to grow. Case in point: e is technically defined by a limit, but the intuition of growth is how it was discovered. Would it be so bad if everyone understood calculus to the “non-rigorous” level that Newton did? That it changed how they saw the world, as it did for him?Ī premature focus on rigor dissuades students and makes math hard to learn. I don’t want to (and can’t) teach an analysis course or train researchers. We’re looking at the sweetness of sugar from the level of brain-chemistry, instead of recognizing it as Nature’s way of saying “This has lots of energy. We’ve created complex mechanical constructs to “rigorously” prove calculus, but have lost our intuition in the process. This lecture/lesson file (pdf) can be used as a lecture on Introduction to Limits (Calculus 1, AP Calculus).Topics covered include:Definition of the. Just a few words on “rigor”.ĭid you know we don’t learn calculus the way Newton and Leibniz discovered it? They used intuitive ideas of “fluxions” and “infinitesimals” which were replaced with limits because “Sure, it works in practice. I can feel the math pedants firing up their keyboards. That’s just not happening with your velocity equation. MATH 1101 - Calculus Preparation (fall only) - is a 1-credit course that introduces a variety of topics of algebra to prepare students for MATH 1106 or MATH. That ring/circle thing we made? You could build it out of several pipe cleaners, separate them, and straighten them into a crude triangle to see if the math really works. I prefer starting with physical, visual examples because it’s how our minds work. That’s great, but it can be hard to relate: honestly, how often do you know the equation for velocity for an object? Less than once a week, if that. Many calculus examples are based on physics. And sometimes the little things are easier to work with. This is a recurring theme in calculus: Big things are made from little things. Calculus showed us that a disc and ring are intimately related: a disc is really just a bunch of rings.

We review how to evaluate these functions, and we show the properties of their graphs. We define polynomial, rational, trigonometric, exponential, and logarithmic functions. In this chapter, we review all the functions necessary to study calculus. This was a quick example, but did you catch the key idea? We took a disc, split it up, and put the segments together in a different way. Calculus is the mathematics that describes changes in functions. Yowza! The combined area of the rings = the area of the triangle = area of circle! Calculus lets us start with $\text (r) (2 \pi r) = \pi r^2$, which is the formula for area! But most of us learn these formulas independently. Welcome to the Calculus course Before we start, just a quick note about the intuition-first. Don’t these formulas seem related in some way? intro » lesson 1 » lesson 2 » lesson 3 » lesson 4 » lesson 5 » lesson 6 » lesson 7 » lesson 8 » lesson 9 » lesson 10 » lesson 11 » lesson 12 » lesson 13 » lesson 14 » lesson 15 » summary. It all fits together.Ĭalculus is similarly enlightening. You know why sugar and fat taste sweet (encourage consumption of high-calorie foods in times of scarcity). You understand why drugs lead to resistant germs (survival of the fittest). My closest analogy is Darwin’s Theory of Evolution: once understood, you start seeing Nature in terms of survival.

It is typed in LaTeX for a beautiful and professional look.I have a love/hate relationship with calculus: it demonstrates the beauty of math and the agony of math education.Ĭalculus relates topics in an elegant, brain-bending manner.
Alternately, the filled-in notes can be used as stand-alone lecture notes. The scaffolded notes can be used with a document camera, or photocopied on a transparency and filled out in class by the teacher (and to be copied by the students). The last 6 pages are the filled-in/complete notes that is used by the teacher. The first 6 pages are the scaffolded notes to be distributed to the students to be filled out. Plus: many examples are given throughout. This lecture/lesson file (pdf) can be used as a lecture on Introduction to Limits (Calculus 1, AP Calculus). Learn calculus from dozens of hands-on, interactive lessons in limits, derivatives, integrals, infinite sums, and more.
