Charles - Know your tutor
My name is Charles Oji and I have two degrees from MIT. Each degree is in "Electrical Engineering and Computer Science". My GPA for undergrad is 4.2/5.0 and 4.6/5.0 for grad school. And I have won several awards including getting the US Green Card under the special category of "Alien of Extraordinary Ability". 5 years later, I became a US Citizen. In July of 2024, I was inducted into the invitation-only, prestigious and honorable "Who's Who in America" group that is run by the 125+ year old "Marquis Who's Who". I have been teaching for over 15 years and I have taught over 8,000 students and professionals. I am a Senior Software Engineer by profession and I have been approved as an Adjunct Professor at Alabama A&M University and Calhoun Community College. I have worked at companies and organizations like Capital One Bank, JP Morgan Chase Bank, Discover Financial Services (DFS), Goldman Sachs and the United Nations (UN). My teaching experience includes over 42 subjects in 7 areas. These subjects include Computer Science (Software Engineering, Java, C#, HTML, SQL, Computer Networks), Math (Algebra, Calculus, Trigonometry, Linear Algebra, Differential Equations, Discrete Math), Software Engineering, Physics, Electrical Engineering, Chemistry and Test-Prep subjects like the SATs, PSATs, ACTs, the Regents, GRE, ASVAB, TOEFL and the GMAT. Last but not least, I am very punctual, very organized, hard working but easy-going. In addition, I make my lessons fun. So connect with me so that we can learn something cool together. I look forward to working with you. Happy Learning, Charles Oji.

Mathematics concepts taught by Charles
Student and Tutor worked on various vector concepts, including identifying orthogonal vectors, computing dot products, finding vector components from initial and terminal points, and performing vector operations. They also calculated magnitudes and standard direction angles of resultant vectors and discussed deriving components from expressions similar to polar notation, in preparation for an upcoming quiz.
Vector Dot Product & Orthogonality
Representing Vectors from Points
Vector Operations: Scalar Multiplication & Subtraction
Magnitude of a Vector
Standard Direction Angle of a Vector
Student and Tutor reviewed vector operations, including unit vectors and finding terminal/initial points, and confirmed the Student's understanding of the midpoint formula. They practiced applying the section formula for points dividing a segment in a given ratio and solved a system of three linear equations using both elimination and matrix inverse methods. The Student plans to complete outstanding lab problems and practice questions from the textbook to solidify their understanding before the next session on Friday.
Solving Systems of Linear Equations: Matrix Method
Vector Operations: Unit Vectors & Points on Segments
Midpoint and Section Formulas for Vector Segments
Solving Systems of Linear Equations: Elimination Method
Matrices: Determinants and Inverse of 3x3
The Student and Tutor reviewed advanced vector concepts in linear algebra, including the geometric interpretation of vector projections and the distinction between mathematical identities and equations. They practiced calculating the distance between parallel planes and applied vector operations, distance formulas, and unit vector definitions in R-squared space. The Student was assigned to complete problems 2E-G, 3, 4, 5, and 6 from Lab 7 for the next session.
Distance Between Two Parallel Planes
The Importance of Showing Detailed Work
Unit Vectors and Their Calculation
Finding a Vector Between Two Points
Geometric Interpretation of Vector Projection
Identity vs. Equation in Mathematics
The Student and Tutor reviewed key concepts in linear algebra, including determining if vectors are orthogonal, calculating the projection of one vector onto another, and finding the distance between a point and a line. The Student practiced these concepts by solving specific problems and collaboratively planning an accelerated study schedule to prepare for an upcoming midterm exam, with assigned practice problems for homework.
Vector Projection: From Shadow to Components
Distance from a Point to a 2D Line
Orthogonality of Vectors
The Student and Tutor focused on Linear Algebra concepts, specifically practicing how to determine if two vectors are orthogonal using the dot product and how to compute the projection of one vector onto another. They also briefly discussed the Student's familiarity with calculus derivatives and identified limits as a challenging area. They scheduled follow-up sessions to continue preparing for the upcoming midterm.
Vector Orthogonality
Vector Dot Product
Vector Projection onto Another Vector
The session focused on fundamental math concepts, including calculating perimeter for squares and hexagons, solving word problems using systematic subtraction with borrowing, and understanding percentage discounts. The Student actively practiced these concepts through homework problems. The Tutor plans to provide a cheat sheet and review more complex carrying problems and long division in future sessions.
