Applied Calculus

    Ended Wed, Apr 2, 2025

I'm back! In this series we will focus rigorously developing concepts in other fields, especially physics, using mathematics. Prerequisites: Differentiation and Basic Integration As an initial goal, we will prove and then apply each formula and physical concept covered content-wise in both AP Physics C Mechanics and E&M exams. However, our derivations and discussions will not be limited to these exams, and this is not strict prep for the exams. We will cover more than just what one must know for these two subjects. I have created this series as a sort of group study for those who wish to use their mathematical background to gain footing in other subjects. It is entirely possible We will first cover Chapters 2-14 of HRK's "[Physics: Volume 1](https://annas-archive.org/md5/f044e83ed41566ab5b5cf336a1e06de5)" for Mechanics, then Chapters 1-7 of Griffith's "Introduction to Electrodynamics." These textbooks focus on the theoretical, mathematical side of Physics and are not mere standard AP textbooks.

Elementary Linear Algebra

    Ended Wed, Feb 14, 2024

(Reboot of my last series) Hi, everyone! I'm proud to present Schoolhouse's first series on Linear Algebra! In this class we will cover all the standard topics of a first class in Linear Algebra (typically take sometime after Calc 2 for greater mathematical maturity, though it can be taken after Calc 3 or before Calculus in the first place.) To be clear, here are the pre-requisites: Algebra (1 and 2, and including Trig) are mandatory. Calculus 1 and 2 are strongly recommended just for maturity, but not required (if you get straight A's in all of Algebra 2 and Trig you should mostly be fine); Calc 3 helps as well (and when I set up my Calc 3 series we will be employing Linear Algebra so if that interests you this course is recommended.) I've taken Multivariable Calculus with Linear Algebra (applied) as well as Linear Algebra itself (proof-based) at Stanford OHS and Stanford ULO, getting an average of B+ on both, and am currently finishing Real Analysis. Generally, here are the topics we will cover (each week): 1. Basic vector operations in R^n 2. Vector Spaces and Subspaces induction technique. 3. Linear independence and Gram-Schmidt 4. Projections and Fourier's Formula 5. Linear Transformations, Properties, and Kernel 6. Matrix operations, special matrices, and matrix properties. 7. Determinants, Linear Systems, Inverse Matrices, and LU decomposition 8. Row, Column, and Null Space, Rank and Nullity 9. Change of Basis, Eigeneverything, and Diagonalizability 10. TBD: QR Decomposition and more on Transpose, Orthogonal Complements, Markov Chains, or anything else. The course expectation is at least 5 hours per week apart from class, office hours, and quizzes. (About 3 hours reading and 2 hours doing homework.) We will meet every Thursday and Saturday at the same time. In class we will not cover all the content (there is simply not enough time), rather we will discuss and go over the proofs the main results, which also appear in the text. We will skip over proofs and results whose proofs we all understand. We will focus on examples and practice in preparation for the assigned exercises and quizzes. We will use Bronson's "Linear Algebra - Algorithms, Applications, and Techniques" as our main text, ([http://ndl.ethernet.edu.et/bitstream/123456789/24629/1/Richard%20Bronson.pdf](http://ndl.ethernet.edu.et/bitstream/123456789/24629/1/Richard%20Bronson.pdf) ) in addition to Stanford's Math 51 text (fragments taken under fair use law which will be posted gradually).

Pre-Algebra to Algebra 1

    Ended Mon, Apr 4, 2022

Hey guys! After receiving a considerable number of requests to host an Algebra series after my recent Geometry w/Trig, I decided to do it! :) Once again, we're going to start from the very beginning of Algebra up to Algebra 1. By the end of the series you will be familiar with... - Single/Multi-varied equations and how to solve them - Rates, Percentages, and Ratios (as well as basic rational equations and how to solve them) -Linear Functions/systems of equations w/Inequalities -Functions (domain, codomain, range, inverse, composite, transformations) -Absolute and pice-wise equations - Exponentials (properties of and functions) -Factoring basic polynomials/quadratics -Forms of quadratics/solving quadratic equations -Complex Numbers -Sequences (arithmetic and geometric). Each session is an hour to an hour and a half. We will have sessions each Monday and Wedsnday. At the end of each session we will test our knowledge with a Quizz. All of my sessions have slides that I share with learners, along with quizlets and relate resources. Homework is optional but recommended and we go over it at the beginning of each session briefly. All of the resources (slides, homeworks, etc. is organized on a google sites which I share with everyone). You can always join even after the series has begun, I'm always open to hosting catch-up sessions :) YOU CAN JOIN THE SERIES AFTER IT'S BEGUN! This is going to be a lot of fun, are you ready?
