Physics Wala Crash Course Lecture: Basic Maths and Matrices

Introduction

• Welcome: Welcome to the channel 'Physics Wala'.
• Objective: Introduction to the crash course on Basic Maths and Matrices for NEET exam preparation.
• Lecture Feature: Facility to download notes from the app.

Basic Maths

Important Points

• No direct questions but fundamental maths is used in solving questions.
• Often students are unable to solve questions because they miss small maths points.

Basic Trigonometry

• Formulas for sine, cosine, and tangent and their reciprocals (like cosecant, secant, and cotangent).
• Values of trigonometric functions at special angles (like 30°, 45°, 60°, 90°).

Radians and Degrees

• 360° = 2π radians
• Conversion of angles into radians and its use.

Identification of Trigonometric Relations

• Identification: sin²θ + cos²θ = 1 etc.

Double Angle Formulas

• Double angle formulas for trigonometric functions like for 2θ.

Addition and Subtraction Formulas for Sine and Cosine

• Formulas for sine (A ± B) and cosine (A ± B).

Maximum and Minimum

• Slope (dY/dX) and its interpretation.
• Process to find maximum and minimum values.

Integration

Basic Integration

• Formulas of integration and their process.
• No defined limit for indefinite integrals.

Definite Integral

• How to integrate with limits.
• Formula: ∫ f(x) dx with limits.

Practice and Suggestions

• Practice sheet exercise: Available as PDF, can be downloaded from the app.
• Availability of Video Solutions: Video solutions the next day.

Conclusion

• Purpose of the lecture: To provide a solid foundation for students for better preparation in the NEET exam.
• Important for further preparation: These notes and video solutions.
• Best Wishes: Best wishes to students from 'Physics Wala'.
