# NCERT Solutions Class 12 Maths Chapter 9 Differential Equations

NCERT Solutions for class 12 maths chapter 9 differential equations utilize the concepts of calculus to introduce a new topic called differential equations. Previously children were taught how to differentiate a given function f with respect to an independent variable, i.e., how to find f ′(x) for a given function f at each x in its domain of definition. Further how to find a function f whose derivative is the function g was also taught to students. Using these concepts a formal definition for differential equations can be given as an equation involving the derivative of the dependent variable with respect to the independent variable. We can also categorize these equations. A differential equation involving derivatives of the dependent variable with respect to only one independent variable is called an ordinary differential equation while partial differential equations are differential equations that involve derivatives with respect to more than one independent variable. NCERT solutions class 12 maths chapter 9 explains these topics in depth with exemplar problems.

Class 12 maths NCERT solutions chapter 9 shows another aspect of calculus. Once children are well-versed with the different methods of differentiating and integrating a function they can smoothly transition to solving the problems in this lesson. NCERT Solutions Chapter 9 differential equations have applications in finding the population growth and decay, determining the glucose absorption by the body, gauging the spread of epidemics as well as in solving various geometric questions involving different types of curves, download the exercises provided in the links below.

November 11, 1675, is when the concept of differential equations was born because of Gottfried Wilhelm Freiherr Leibnitz (1646 - 1716) who gave a calculus identity. Leibnitz was actually interested in the problem of finding a curve whose tangents were prescribed. This led him to discover many associated concepts of differential equations. With several researchers working on the complexity of this topic the equations took a form as we see them today. The NCERT solutions class 12 maths has many such facts as well as tips to help kids combat monotony and study with enthusiasm. Given below are the links to all the exercise solutions.
