Trigonometric Functions: Basics and Applications

This lecture covers the basics of trigonometric functions, including differential calculus, integration techniques, exponential and logarithmic functions, and hyperbolic functions. The instructor explains the properties of trigonometric functions, such as sine, cosine, and tangent, and their applications in geometry and physics. The lecture also delves into the trigonometric circle, angle classification, and trigonometric ratios in right triangles. Practical examples, like calculating heights and distances using trigonometry, are discussed. Additionally, the lecture explores graphs of trigonometric functions and their properties, such as periodicity and odd/even functions.
