Exercise 9.3 Class 11 Maths
Important Short Notes of Exercise 9.3 Class 11 Maths written by Professor Asad Khalid Suib. These notes are very helpful in the preparation of Exercise 9.3 Maths Class 11 for the students of Mathematics of the Intermediate and these are according to the paper patterns of all Punjab boards.
Summary and Contents:
Topics which are discussed in the notes are given below:
- Our comprehensive Exercise 9.3 Class 11 Maths will ensure you're fully prepared for your exams.
- Solution of the Exercise 9.3 in Chapter No. 9: Fundamentals of Trigonometry in 11th Class Mathematics.
- The values of the Trigonometric Functions of angles 0°, 90°, 180°, 270°, 360°.
- When terminal line lies on the x- axis or the y- axis, the angle q is called a quadrantal angle.
- Now we shall ind the values of trigonometric functions of quadrantal angles 0°, 90°, 180°, 270°, 360° and so on. (a) When q = 0°
- When q = 90° The point (0, 1) lies on the terminal side of angle 90°.
- When q = 180° The point (-1, 0) lies on the terminal side of angle 180° ⇒ x = -1 and y = 0.
- When q = 270° The point (0, -1) lies on the terminal side of angle 270° ⇒ x = 0 and y = -1
- Find the values of all trigonometric functions of (i) 360°
- Find x, if tan245° - cos260° = x sin 45° cos 45° tan 60°.
- Find the values of the trigonometric functions of the following quadrantal angles:
- Domains of Trigonometric functions and of Fundamental Identities
- We list the trigonometric functions and fundamental identities, learnt so far mentioning their domains as follows:
- Now we shall prove quite a few more identities with the help of the above mentioned identities.
