**3. What are some important points to remember while solving Class 11 RS Aggarwal Questions for Chapter 15 Trigonometric or Circular functions?**

While solving Class 11 Chapter 15 from RS Aggarwal, students must pay attention to the concepts as all the questions are based strictly on the topics taught in the chapter. Here are some important concepts that students must pay special attention to before starting to attempt Chapter 15 Trigonometric and Circular functions from Class 11 RS Aggarwal:

The relationships between different angles or sides of a right angle triangle are called T-ratios or Trigonometric ratios.

Trigonometric functions are elementary functions, the focus of which are angles. These trigonometric functions include Sine, Cosine, Tangent, Cotangent, Secant, and Cosecant.

Constituent angles are those angles whose algebraic sum is called compound angles.

Trigonometric functions have extremely diverse applications.
