Trigonometric or Circular Functions: Class 11 RS Aggarwal Chapter 15 Solution Summary

This chapter focuses on explaining the circular functions used in trigonometry. These functions are derived by calculating the values of the trigonometric ratios of angles ranging on a Cartesian plane. Previously, you have learned how these ratios behave within 90 degrees. You will use the same knowledge to learn these advanced concepts of ratios based on 360 degrees on a plane. The exercises in Class 11 RS Aggarwal Chapter 15 will deliver conceptual questions to help you analyse your problem-solving skills. Download and use RS Aggarwal Class 11 Solutions Trigonometry as reference. Take a quick look at the summary of this solution.

In the first exercise, the sums are based on the basic trigonometric identities but the values of the ratios show the locations of the angles in different quadrants of the Cartesian plane. Concentrate on the values of the ratios and figure out how to solve these questions. You can refer to the solutions, to begin with, the exercise, and gather confidence to approach these questions. Learn how the teachers have suggested solving these problems in Class 11 Maths RS Aggarwal Solutions Trigonometry. Use your basic concepts too to understand these advanced methods and enhance your problem-solving skills.

In the same exercise, you will find sums related to angles multiple to the common angles generally used to frame sums. Focus on the trick and understand how these questions can be tackled easily. By simply following the steps mentioned in the solutions, you can easily trim down these difficult sums into the basic conceptual format and answer them accordingly. Pay attention to every step of RS Aggarwal Solutions Class 11 Chapter 15 and learn how simple these questions can be.

In the next exercise, you will get sums related to multiple angles that can be trimmed down to simpler ones. Here, you will have to find out how these angles can be partitioned to reduce the complex trigonometric expressions into simpler ones and find the answer casually. Every question included in this exercise has a twist. Find the hints and seek the assistance of the RS Aggarwal Class 11 Maths Chapter 15 Solution to resolve your doubts. Practice answering these questions using the solution as a reference to gain confidence. Remember to use the trigonometric identities you have learned in the previous classes.

The same exercise will also ask questions related to trigonometric proofs. Concentrate on both the sides of the equation given and the angles provided in each term. Learn how to transform them as per your need and proceed. Each step of an answer to this type of question is very important. Remember you have to achieve the trigonometric expression given on the other side. Hence, follow how the teachers have approached these questions in the RS Aggarwal Class 11 Trigonometry Solutions and learn how to solve them using the basic tricks.
