About
Hi, my name's Jose, I'm an upcoming senior and an international student. I love listening to Indie music, watching 80s movies, and reading in my spare time. I enjoy math because it allows me to express myself artistically, and tutor for the mere sake of those aha moments.

Capitalism v. Socialism: Fundamental Texts (UNIT 2)
- 21st session
Book List: https://docs.google.com/document/d/1rqjpwv7Xn5WSZJJXzjFNq7QN-h-IvwwlyNrBZG9Z2SM/edit?usp=sharing Office Hours: https://schoolhouse.world/series/1639?celebrate The aim of this series is to analyze Capitalist and Socialist Theory from an objective point of view. We will read Adam Smith and Karl Marx, among many, many more. We will read their critics, discuss the ideas we read in our sessions, and (optionally) write essays analyzing, comparing, and contrasting their ideas. This series is just the second part--on the role of government (liberty v. equality). How we structure each session will be based on this guide: http://www.greatbooks.org/wp-content/uploads/2014/12/Shared-Inquiry-Handbook.pdf Sessions will be added continually.

Calculus · Series
Comprehensive Calculus: Limits, Derivatives, and Integrals
- 22nd session
Finally! The long-awaited series in Calculus is here. Main resources being used: AoPS and Khan Academy Pre-requisites: Trigonometry, Algebra 1, Algebra 2, and Precalculus (recommended but not required). The session descriptions are posted below, so please check them out! This is the first of three series I will be hosting, covering Calculus 1, 2, and 3. After each series ends I will host the next. In this course we will be covering the following: LIMITS AND CONTINUITY (Unit 1) - Introduction to limits - One and two-sided limits - Creating tables to approximate limits; approximating limits using tables - Limits of composite functions - Evaluating limits through direct substitution -Limits of trigonometric and piecewise functions -Evaluating limits by rationalizing and by using trigonometric identities -Squeeze theorem and applications -Introduction to continuity and types of discontinuities -Continuity at a point and over an interval -Removing discontinuities -Limits at infinity and limits at infinity of quotients -The Intermediate Value Theorem -The formal epsilon-delta definition of a limit DERIVATIVES (Unit 2): -Introduction to derivatives and notation -Average rate of change and the secant line -Instantaneous rate of change and the tangent line -The formal and informal definition of a derivative using limits -Equation of the tangent line of a function at a point -Estimating derivatives graphically and algebraically -Differentiability at a point and over an interval (connection to continuity) -Evaluating derivatives using the power rule, sum rule, product rule, quotient rule, and chain rule (including proofs of all the rules) -Derivative of sin(x), cos(x), tan(x), csc(x), sec(x), cot(x), ln(x), e^x, a^x, and log_a(x) (including a derivation of all of the formulas) -Derivative of inverse functions and inverse trigonometric functions -Second derivatives, implicit differentiation, and related rates -Position, velocity, and acceleration problems -Local linearity and linear approximations to functions -L'Hôpital's rule and the special case of L'Hôpital's rule -The Mean Value Theorem for derivatives, the Extreme Value Theorem, and Rolle's Theorem -Finding critical points, local minima and maxima, increasing and decreasing intervals of a function -Finding absolute extrema over closed intervals and over the entire domain of a function -Introduction to concavity -The Second Derivative Test and points of inflection -Optimization INTRODUCTION TO INTEGRATION (Unit 3) -introduction to accumulation of change -Left and right Riemann sums; over and under-approximation -Midpoint and trapezoidal sums -Definition of indefinite integral using as the limit of Riemann sums -The Fundamental Theorem of Calculus (including the proof), antiderivatives, and definite integrals -Interpretation of accumulation functions: negative definite integrals, definite integrals over a single point; graphical interpretation and evaluation. -Integrating sums of functions, switching the bounds of integration, and with functions as bounds. -The reverse power rule, u-substitution, and integration by parts -Antiderivatives of all the previously mentioned functions -Improper integrals
