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 Student received an introduction to derivatives, including their definition, calculation using limits, and graphical interpretation. The Tutor explained the power rule, constant rule and covered applications of derivatives in physics and economics. The Student practiced applying derivative rules to example problems, and will continue working with derivatives in the next session.
Graphical Interpretation of Derivatives
Applications of Derivatives
Basic Derivative Rules
Definition of a Derivative
Calculating Derivatives Using the Limit Definition
The Student and Tutor reviewed limits using graphical examples and algebraic techniques including absolute values. They worked through problems requiring the student to determine limits from graphs, considering one-sided limits and cases where limits do not exist. The session concluded with an introduction to derivatives and their relation to the slope of a function.
Limits and Function Values
One-Sided Limits
Limits with Absolute Values
Indeterminate Forms and Algebraic Manipulation
Limits Approaching Infinity
Introduction to Derivatives
The Tutor and Student discussed limits, continuity, and domain, using GeoGebra to visualize functions and their limits. They worked through examples involving piecewise functions and one-sided limits. The Student was advised to send the textbook when available to help with upcoming lessons.
