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 focused on indefinite integrals and the substitution rule in calculus, with the tutor explaining the technique using composite functions and demonstrating its application through examples. The student and tutor also practiced evaluating integrals over infinite intervals to determine convergence or divergence, and worked through various indefinite integral problems, including those involving trigonometric and inverse trigonometric functions.
Substitution Rule in Integration
Indefinite Integrals and Convergence
Separating Integrals
Inverse Trigonometric Integrals
The student and tutor reviewed and practiced calculating the areas of various geometric shapes, including squares and circles, and composite shapes. They worked through problems involving finding the area of shaded regions and utilized formulas for squares and circles. The tutor assigned additional practice exercises to prepare for an upcoming math test.
Composite Area Calculations
Area of a Semi-Circle
Area of Shapes Composed of Grids
Calculating Area of Basic Shapes
The Tutor and Student reviewed calculus concepts, focusing on definite integrals, the Fundamental Theorem of Calculus, integration techniques including substitution, and the geometric interpretation of integrals as areas. They practiced converting limits of summation to integrals and evaluating integrals using properties and geometric formulas, with plans to continue lessons weekly until the final exam.

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.
