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 and student reviewed and solved advanced problems in trigonometry, coordinate geometry, and conic sections. They practiced techniques for solving trigonometric equations, finding tangents to circles, and deriving parabola equations. The next session will continue with t-formulae, and the student will submit a solved homework problem.
Solving Trigonometric Equations with Substitution
Trigonometric Identities and the t-formulae
Tangents to Circles: Discriminant Method
Parabola: Cartesian Equation from Focus and Directrix
The tutor and student reviewed concepts related to normal distribution, including Z-scores, percentiles, and the approximation of binomial distributions using normal distributions. They practiced solving problems involving these concepts and touched upon hypothesis testing for sample means, with the tutor offering to clarify specific areas of confusion.
Normal Distribution & Standardisation
Percentiles and Inverse Normal Distribution
Approximating Binomial with Normal Distribution
The tutor and student worked through a series of mathematics problems covering polynomial roots, implicit differentiation, radical and exponential equations, vector algebra, linear transformations, and complex numbers. They practiced problem-solving techniques and discussed concepts like invariant lines and the nature of imaginary roots, with plans to review parabola and hyperbola topics in the next session.
Roots of Polynomials and Complex Numbers
Implicit Differentiation and Gradients
Vector Parallelism and Cross Products
Exponentials and Logarithms: Equating Bases
The Tutor and Student reviewed statistical concepts including binomial distribution and probability. They then delved into regression and correlation, learning how to linearize exponential models and perform hypothesis tests for zero correlation. The next session will focus on normal distribution, with the student identifying specific sections to review.
Product Moment Correlation Coefficient (r)
Hypothesis Testing for Zero Correlation
Exponential Model Transformation to Linear Form
The tutor and student worked through various mathematics problems covering vectors, partial fractions, complex numbers, binomial expansion, trigonometry (cosine and sine rules), and solving equations with trigonometric substitutions. They practiced problem-solving techniques and discussed concepts relevant to the student's syllabus and future learning.
Vector Cross Product Properties
Partial Fractions and Series Summation
Complex Numbers: Modulus and Argument
Binomial Expansion Coefficients
Trigonometric Rules: Cosine Rule
The session focused on hypothesis testing within the context of binomial distributions. The student practiced identifying test statistics, formulating null and alternative hypotheses, and determining critical regions. The tutor guided the student through several textbook examples, reinforcing the steps for conducting hypothesis tests and drawing conclusions.
Test Statistics and Critical Regions
Binomial Distribution in Hypothesis Testing
Significance Level and p-values
Hypothesis Testing: Null and Alternative Hypotheses
