Dr. Theertha - Know your tutor
I am Dr. Theertha Nair A. I am currently working as a college lecturer in Kerala, and teaching has always been part of my life. Both my parents are teachers, and from childhood I grew up watching them, slowly dreaming of becoming a college teacher one day—and here I am. While teaching in college, I met many students who struggled even with basic concepts, not because they lacked ability, but because their foundations were weak. I don’t blame students or teachers; both share that responsibility. For me, mathematics is not just numbers—there is a beautiful story behind every concept. I believe teachers should help students see that story and fall in love with the subject. I may not change the world, but if I can make a small positive change for a small group of future learners, that itself is meaningful. And that is why I am here. I started learning maths from scratch and slowly grew into a Doctor of Mathematics, so I know the struggles well. In my class, everything is made to make sense. Instead of only asking “why”, I help students think “why not”. If you want to enjoy maths, understand it deeply, and build real confidence—not just learn formulas—this class is for you.

Class overview
I focus on building strong fundamentals from the very beginning, ensuring students truly understand concepts instead of memorizing formulas. I encourage curiosity and questions, helping students see the story behind every number, and guide them from asking “why” to thinking “why not.” My classes are designed to make learning enjoyable, develop real understanding, and inspire a lasting love for mathematics. Having taught over 200 students, I excel in adapting lessons to different learning levels, using interactive methods, examples from real life, and personalized guidance. I believe every student can excel when their fundamentals are strong, and I aim to build confidence, logical thinking, and problem-solving skills so students not only perform well in exams but also develop a genuine interest and passion for mathematics that lasts a lifetime.

Mathematics concepts taught by Dr. Theertha
The Tutor introduced complex numbers to the Student, explaining their 'a + bi' form and the concepts of real and imaginary parts. They practiced identifying these parts, calculating with square roots of negative numbers, and determining powers of 'i' using a remainder-based method. The Tutor plans to continue with further sections on complex numbers in the next session.
Complex Numbers: Standard Form
The Imaginary Unit 'i'
Simplifying Powers of 'i'
Operations with Square Roots of Negative Numbers
The Tutor and Student reviewed concepts related to polynomial roots, including Vieta's formulas and linear transformations of roots. They worked through several examples and practice problems from the textbook, focusing on problem-solving techniques for exam-style questions. The Student was encouraged to practice more problems from the same chapter and a recommended website.
Deriving Polynomial Identities
Complex Conjugate Roots Theorem
Vieta's Formulas
Transforming Polynomial Roots
The student and tutor reviewed complex numbers, covering geometric rotations, properties of purely real/imaginary numbers, and conditions for complex conjugate roots. They practiced solving equations, finding square roots of complex numbers, and determining loci, with plans to move to roots of polynomials in the next session.
Finding Square Roots of Complex Numbers
Cartesian Equation from Argument
Loci of Complex Numbers
Complex Roots of Polynomials with Real Coefficients
Geometric Interpretation of Multiplying by 'i'
The Tutor and Student reviewed complex numbers, focusing on the Argand plane, properties of 'i', complex conjugates, and the geometric representation of complex numbers and loci. They practiced simplifying powers of 'i', determining the nature of sums and products of complex numbers, and understanding graphical representations of inequalities and conditions on complex numbers. The Tutor assigned practice questions for the student to complete before the next class.
The Argand Plane and Complex Number Representation
Properties of Complex Conjugates
Roots of Polynomials with Real Coefficients
Geometric Interpretation of Complex Number Operations (Loci)
The student and tutor reviewed Poisson and Binomial distributions, focusing on identifying when to use each and practicing problem-solving techniques for both. They worked through examples, covered the conditions for using Poisson distribution, and discussed the approximation of Binomial by Poisson when n is large and p is small. The next session will cover specific topics from the student's Core Pure 1 mathematics textbook.
Poisson Distribution Formula and Application
Poisson Distribution vs. Binomial Distribution
Discrete vs. Continuous Random Variables
Approximating Binomial with Poisson
The tutor and student reviewed trigonometric identities and the t-substitution method (t = tan(θ/2)). They practiced solving various trigonometric equations, deriving formulas, and applying algebraic manipulations. The next session is planned to cover statistics, specifically Poisson distribution.
T-Substitution (Tangent Half-Angle Substitution)
Trigonometric Identities and Their Application
Quadrants and CAST Rule
Solving Trigonometric Equations Algebraically
