In the previous chapters, we have learnt that all trigonometric functions are periodic functions, so we shall draw their graphs on the intervals of lengths equal to their periods. In order to enhance the performance of students in Class 11 exam, we at BYJUâ€™S have formulated the RD Sharma Class 11 Solutions for Maths under. Exercise-wise problems are solved in a step by step method to help students understand the concepts easily. Students are advised to practice the solutions on a regular basis to obtain good marks in their exams. The solutions are available in the pdf format, which can be downloaded easily from the links provided below.
Chapter 6- Graphs of Trigonometric Functions contains three exercises and the RD Sharma Solutions present in this page provide solutions to the questions present in each exercise. Now, let us have a look at the concepts discussed in this chapter.
- Graph of the sine function.
- Graph of the cosine function.
- Graph of the tangent function.
- Graph of cosecant function.
- Graph of cotangent function.
- Graph of secant function.

So, f (x) = 3 sec (x) is a periodic function with period Ï€. So, we will draw the graph of f (x) = 3 sec (x) in the interval [0, Ï€]. The values of f (x) = 3 sec (x) at various points in [0, Ï€] are listed in the following table:
x |
0 (A) |
Ï€/2 (B) |
-Ï€/2 (C) |
Ï€ (D) |
-3Ï€/2 (E) |

The required curve is:
3. f (x) = cot 2x
Solution:
We know that f (x) = cot x is a periodic function with period Ï€.
So, f (x) = cot (2x) is a periodic function with period Ï€. So, we will draw the graph of f (x) = cot (2x) in the interval [0, Ï€]. The values of f (x) = cot (2x) at various points in [0, Ï€] are listed in the following table:

4. f (x) = 2 sec Ï€x
Solution:
We know that f (x) = sec x is a periodic function with period Ï€.
So, f (x) = 2 sec (Ï€x) is a periodic function with period 1. So, we will draw the graph of f (x) = 2 sec (Ï€x) in the interval [0, 1]. The values of f (x) = 2 sec (Ï€x) at various points in [0, 1] are listed in the following table:

The required curve is:
5. f (x) = tan^{2}Â x
Solution:
We know that f (x) = tan x is a periodic function with period Ï€.
So, f (x) = tan^{2}Â (x) is a periodic function with period Ï€. So, we will draw the graph of f (x) = tan^{2}Â (x) in the interval [0, Ï€]. The values of f (x) = tan^{2}Â (x) at various points in [0, Ï€] are listed in the following table:
