Basic Mathematics for NEET Preparation

Introduction

  • Lecturer: Dr. Ayu (NEET cleared in 1hr 40 mins)
  • Focus on making complex concepts seem easy and solving problems without pen/paper

Key Mathematical Elements Covered

Logarithms

  1. Definitions and Properties
  2. Common vs Natural Logarithms
  3. Basic Logarithm Identities
    • Product Rule: log(A*B) = log(A) + log(B)
    • Quotient Rule: log(A/B) = log(A) - log(B)
    • Power Rule: log(A^B) = B * log(A)
    • Change of Base: log_base(A) = log(A)/log(base)
  4. Special Values (Base 10 and e)
  5. Basic Conversion Techniques between degrees and radians
