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 Tutor and Student explored measurement concepts, contrasting the imperial and metric systems and discussing the historical importance of measurement. They practiced calculating perimeter and area, understanding the difference between length and surface measurements and their respective units.
Measurement Systems: Metric vs. Imperial
Perimeter vs. Area
Tools for Measurement
The student and tutor reviewed methods for estimating areas under curves using rectangles. They worked through two problems involving approximating areas under parabolas, one from 0 to 3 and another from -1 to 2, utilizing right endpoints for rectangle height determination. The session is preparing the student for their upcoming Calculus I final exam.
Estimating Area with Rectangles
Right Endpoint Rule
Antiderivatives
The session focused on understanding and applying anti-derivatives to calculate the area under curves, building upon previous lessons about approximating area with rectangles. The student practiced finding general anti-derivatives for various functions, including polynomial and trigonometric functions, and learned techniques for simplifying complex expressions before integration. The next class will cover more complicated integrals, such as those involving chain rules.
Introduction to Antiderivatives (Integrals)
Simplifying Integrals with Algebraic Manipulation
Antiderivative of eˣ
Properties of Antiderivatives
Antiderivatives of Trigonometric Functions
Approximating Area with Rectangles
The Tutor and Student reviewed fundamental geometric area calculations, starting with squares and rectangles and progressing to triangles and circles. They explored the conceptual basis of area through multiplication and the historical derivation of formulas like those for triangles and circles, including the introduction of pi.

Exam Preparation and Time Management
The Tutor and Student worked on trigonometry, focusing on solving triangles using the Law of Sines and understanding the ambiguous case. They practiced calculating triangle areas and discussed strategies for finding sine values of various angles, including those greater than 90 degrees. The Tutor outlined potential future topics in pre-calculus, such as vectors and differential equations.
