Luis Armando - Know your tutor
My name is Luis Casso, students can call me Lucho. I've been an unofficial tutor for three years already, and my passion lies in teaching mathematics to anyone who needs help. I helped students from various academic levels, ranging from the last year of high school to undergraduate college students. I can help with any topic up to Calculus I, and I will find time for teaching and making sure that every student who requires my help finds all the sources they need. As a math major student, I got to understand how maths could be harder for any student and how that made every high school student to have some sort of rejection towards the topic, but I personally wanted to become a math teacher because I think that everyone can learn math, and math can be used to teach not only as a school subject, but a way to understand the world and how it works. That is why teaching is my passion.

Class overview
My teaching style goes hand in hand with making sure students understand the why behind things. Every formula has a reason to exist, and students need to grasp the logical process behind the terminology for a more solid kind of learning — rather than just memorizing formulas they’ll likely forget. I’m very patient and interactive when teaching, and I always try to go at a pace that students find comfortable. The topics I can teach are varied in content, and I find it easy to identify areas of mathematics that require specific logical processes. At the same time, I can teach different strategies and tricks so that students learn through mnemonic devices or visual examples — helping them understand how to approach any exercise or problem they encounter. I have experience working with several students and have been able to connect with them in different ways to help them understand the problems presented. Once they become comfortable with the concepts, they reach the solutions much more quickly.

Mathematics concepts taught by Luis Armando
The session provided a focused review of calculus concepts, including the instantaneous rate of change (derivative) and optimization problems. The tutor and student practiced finding derivatives using the limit definition and solved a problem to minimize average cost, preparing the student for their midterm.
Optimization: Minimizing Average Cost
Finding Derivatives Using the Limit Definition
Instantaneous Rate of Change (Derivative)
Interpreting Graphically: Points and Slopes
The session involved a review of calculus concepts, including limits, the Squeeze Theorem, the Intermediate Value Theorem, continuity, horizontal asymptotes, and derivatives. The student practiced solving problems involving indeterminate forms, analyzing discontinuities, and applying differentiation rules. The tutor provided guidance and clarified concepts in preparation for the student's upcoming exam.
Rationalizing the Numerator/Denominator
Horizontal Asymptotes and Limits at Infinity
Intermediate Value Theorem (IVT)
The Squeeze Theorem
Continuity and Discontinuity
The tutor and student reviewed various function graphs, including polynomial, reciprocal, trigonometric, inverse trigonometric, exponential, and logarithmic functions. They practiced identifying graph behaviors, understanding inverse functions, and applying limit concepts to analyze function behavior and solve problems. The session also briefly touched upon the relationship between position, velocity, and acceleration through derivatives, with plans to continue reviewing limits and derivatives in the next session.
Graphing Polynomial Functions (Even & Odd Exponents)
Reciprocal Functions (Even & Odd Negative Exponents)
Trigonometric Functions (Sine
Cosine
Tangent)
Inverse Trigonometric Functions (Arc Sine
Arc Cosine
Arc Tangent)
The student and tutor reviewed the Squeeze Theorem to evaluate limits of complex functions. They worked through examples involving exponential and trigonometric functions, applying the theorem to determine limits at infinity. The session prepared the student for their upcoming midterm.
Squeeze Theorem
Limit of Exponential Functions
Bounds of Trigonometric Functions
Applying Squeeze Theorem to Rational Functions
The Student and Tutor focused on calculus concepts, specifically limits and continuity. They worked through various problems involving rational functions, cubic expansions, and square root expressions, practicing factoring techniques and algebraic manipulation to evaluate limits. The Tutor encouraged the Student to continue practicing these methods.
Domain and Restrictions
Factoring and Simplifying Rational Functions
Evaluating Limits
Algebraic Identities in Limits
The tutor and student reviewed key differentiation rules in Calculus, including the product, quotient, and chain rules, and then delved into exponential growth and decay models. They practiced solving problems related to these concepts, including calculating half-life and decay rates, and planned to prepare for an upcoming midterm focusing on these topics.
