Trigonometric Functions are introduced in Exercise 3.1 of the NCERT Solutions for Class 11 Maths. In Ex 3.1 Class 11 solution, the two units of angular values, degree and radian, are explained in depth. In the most recent Class 11 Maths NCERT Solutions, the technique of unit conversion is also demonstrated. Students will also learn how to convert a Trigonometric Value to a different form.

Embibe offers free 3D interactive videos while making learning fun for students. Besides these videos, students can also use Embibe’s books, Exemplars, and other content for free. If students wish to score good marks, they can start practicing through the Embibe 3D and Exemplar videos. Below are the important topics covered by Embibe:

Below are the concepts taught in NCERT Solutions for** Class 11 Maths Exercise 3.1**:

Sr. No. | Topic Name |

6 | Relation Between Degree and Radian |

Below are some vital points to remember from the ex 3.1 of Class 11 Maths:

- The measure of an angle is the amount of rotation from the initial side to the terminal side.
- The sense of an angle is positive or negative according to the initial side rotates in an anti-clockwise or clockwise direction to get the terminal side.
- Sexagesimal system:

(a) 1 right angle =90 degrees =90°

(b) 1°=60 minutes =60′

(c) 1’=60 seconds =60″ - Centesimal system:

(a) 1 right angle =100 grades =100g

(b) 1g=100 minutes =100′

(c) 1’=100 seconds =100″ - Circular system:

(a) The unit of measurement is the Radian. One radian is the measure of an angle subtended at the centre of a circle by an arc of length equal to the radius of the circle.

(b) π radians=180°

**Ans: **All Trigonometric Identities are built on the foundation of the six Trigonometric Ratios. The arithmetic functions are Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent. The Adjacent, Opposing, and Hypotenuse sides of a right triangle are used to define all of these Trigonometric Ratios.
