NCERT Exemplar Class 12 Maths Solutions Chapter 9 Differential Equations
NCERT Exemplar Class 12 Maths Solutions Chapter 9 provides an understanding of equations that relate to one or more functions and their derivatives. In this continually changing world, describing how things change with respect to several factors is very important. The representation of this information is termed as a differential equation. A differential equation is a great way to express a set of information, but it can be hard to solve or formulate. One of the essential languages of Science is that of differential equations.
