About Class 11 Maths Exercise 9.3
The third section of chapter 9 from NCERT Solution for Maths class 11th is about explaining the aforementioned terms and equations. These are slope-intercept form, intercept form, and normal forms as the main ones. The slope intercepts form and intercept form are part of one single equation whose graph representation will be a straight line. Ax + By + C = 0, is the linear equation or general linear equation.
The value of the A and B constant is not zero. Now, you will see if the equation is reduced or split into half. You will get two different equations. One is highlighted under the section of the slope-intercept paragraph and the other is given in intercept form.
Normal form of Linear Equations
The difference between the other two equations is that normal forms change the linear equation entirely by implying trigonometry. This prove Ax + By + C = 0 or Ax + By = -C, has same value. The students who have proven an excellent understanding of the fundamental rules of trigonometry applications, sign, and linear equations shall find the normal form is much more useful and easy. Get the explanation is the complete form for this topic from NCERT Solutions Class XI Mathematics.
Exploring the distance of a point
Calculating the distance, angles, elevations, and other similar facts are the major practical operation that you will find useful in your daily life. The students who are looking to make a career in the Art or engineering field might find it important. Though it is just some small part of the concept that you have already learned till high school mathematics. When looking at figure, you might feel that it will be a difficult concept to understand, but even little knowledge of the solving linear equation can help you understand the entire part.
Examples and Questions of Exercise 9.3
There are only two examples given in the third part of the chapter. This will provide you with little idea of how you can follow the step to get the answer. By now you must have understood that in mathematics not just the solution, but the step also matters. In 11th NCERT Textbook exercise 9.3 you shall be given plenty of questions to solve.
However, among all the questions there are few questions that has the use of trigonometry. So, for the concepts of straight lines, must go through the basics of trigonometry.
