Concept of elementary row and column operations.

Derivatives of logarithmic and exponential functions. Integration as inverse process of differentiation. Definite integrals as a limit of a sum, Fundamental Theorem of Calculus without proof.

Definition, order and degree, general and particular solutions of a differential equation. Solutions of linear differential equation of the type given in the syllabus.

A linear differential equation is always of the first degree but every differential equation of the first degree need not be linear. Solution of Differential Equations A solution of a differential equation is a relation between the variables, not involving the differential coefficients, such that this differential equation class 12 and the derivative obtained from it satisfy the given differential equation.

General Solution If the solution of the differential equation contains differential equation class 12 many independent arbitrary constants as the order of the differential equation, then it is called the general solution or the complete integral of the differential equation.

Particular Solution Solution obtained by giving particular values to the arbitrary constants in the general solution is called a particular solution.

Solution of a differential equation is also called its primitive. Differentiate the equation successively n times to get n equations.

Solutions of Differential Equations of the First Order and First Degree A differential equation of first degree and differential equation class 12 order can be solved by following method. Let a, 0 be the centre of the circle.

Since it touches the y-axis at origin, its radius is a. Now, the equation of the circle with centre a, 0 and radius a is Differentiating equation 1 with respect to x, we get: Now, on substituting the value of a in equation 1we get: This is the required differential equation.

Form the differential equation of the family of parabolas having vertex at origin and axis along positive y-axis. The equation of the parabola differential equation class 12 the vertex differential equation class 12 origin and the axis along the positive y-axis is: Differentiating equation 1 with respect to x, we get: Dividing equation 2 by equation 1we get:
