Application of Ordinary Differential equation in daily life - YouTube To solve a math equation, you need to decide what operation to perform on each side of the equation. We can conclude that the larger the mass, the longer the period, and the stronger the spring (that is, the larger the stiffness constant), the shorter the period. The negative sign in this equation indicates that the number of atoms decreases with time as the isotope decays. By solving this differential equation, we can determine the velocity of an object as a function of time, given its acceleration. The applications of second-order differential equations are as follows: Thesecond-order differential equationis given by, \({y^{\prime \prime }} + p(x){y^\prime } + q(x)y = f(x)\).

Graphical representations of the development of diseases are another common way to use differential equations in medical uses. So, with all these things in mind Newtons Second Law can now be written as a differential equation in terms of either the velocity, v, or the position, u, of the object as follows. It is often difficult to operate with power series. It involves the derivative of a function or a dependent variable with respect to an independent variable. First Order Differential Equation (Applications) | PDF | Electrical Newtons law of cooling can be formulated as, \(\frac{{dT}}{{dt}} = k\left( {T {T_m}} \right)\), \( \Rightarrow \frac{{dT}}{{dt}} + kT = k{T_m}\). if k>0, then the population grows and continues to expand to infinity, that is.
