(i)\)At \(t = 0,\,N = {N_0}\)Hence, it follows from \((i)\)that \(N = c{e^{k0}}\)\( \Rightarrow {N_0} = c{e^{k0}}\)\(\therefore \,{N_0} = c\)Thus, \(N = {N_0}{e^{kt}}\,(ii)\)At \(t = 2,\,N = 2{N_0}\)[After two years the population has doubled]Substituting these values into \((ii)\),We have \(2{N_0} = {N_0}{e^{kt}}\)from which \(k = \frac{1}{2}\ln 2\)Substituting these values into \((i)\)gives\(N = {N_0}{e^{\frac{t}{2}(\ln 2)}}\,. Electrical systems also can be described using differential equations. Examples of applications of Linear differential equations to physics. ), some are human made (Last ye. A differential equation is a mathematical statement containing one or more derivatives. In the description of various exponential growths and decays. As with the Navier-Stokes equations, we think of the gradient, divergence, and curl as taking partial derivatives in space (and not time t). Application of Partial Derivative in Engineering: In image processing edge detection algorithm is used which uses partial derivatives to improve edge detection. this end, ordinary differential equations can be used for mathematical modeling and Nonlinear differential equations have been extensively used to mathematically model many of the interesting and important phenomena that are observed in space. They are used in many applications like to explain thermodynamics concepts, the motion of an object to and fro like a pendulum, to calculate the movement or flow of electricity. The exploration guides talk through the marking criteria, common student mistakes, excellent ideas for explorations, technology advice, modeling methods and a variety of statistical techniques with detailed explanations. A differential equation involving derivatives of the dependent variable with respect to only one independent variable is called an ordinary differential equation, e.g., 2 3 2 2 dy dy dx dx + = 0 is an ordinary differential equation ..

The CBSE Class 8 exam is an annual school-level exam administered in accordance with the board's regulations in participating schools. Solution of the equation will provide population at any future time t. This simple model which does not take many factors into account (immigration and emigration, for example) that can influence human populations to either grow or decline, nevertheless turned out to be fairly accurate in predicting the population. In geometrical applications, we can find the slope of a tangent, equation of tangent and normal, length of tangent and normal, and length of sub-tangent and sub-normal. Radioactive decay is a random process, but the overall rate of decay for a large number of atoms is predictable.

Mixing problems are an application of separable differential equations. Let T(t) be the temperature of a body and let T(t) denote the constant temperature of the surrounding medium. But differential equations assist us similarly when trying to detect bacterial growth. Then we have \(T >T_A\). Hence, the order is \(1\). Microorganisms known as bacteria are so tiny in size that they can only be observed under a microscope. chemical reactions, population dynamics, organism growth, and the spread of diseases.
