The solution which contains as many arbitrary constants as the order of the differential equation is called the general solution and the solution free from arbitrary constants is called particular solution.<br>(vii) To form a differential equation from a given function, we differentiate the function successively as many times as the number of arbitrary constants in the given function and then eliminate the arbitrary constants.<br>(viii) The order of a differential equation representing a family of curves is same as the number of arbitrary constants present in the equation corresponding to the family of curves.<br>(ix) \u2018Variable separable method\u2019 is used to solve such an equation in which variables can be separated completely, i.e., terms containing x should remain with dx and terms containing y should remain with dy.<br>(x) A function F (x, y) is said to be a homogeneous function of degree n if F (\u03bbx, \u03bby )= \u03bb<sup>n<\/sup>&nbsp;F (x, y) for some non-zero constant \u03bb.<br>(xi) A differential equation which can be expressed in the form dy\/dx = F (x, y) or dx\/dy = G (x, y), where F (x, y) and G (x, y) are homogeneous functions of degree zero, is called a homogeneous differential equation.<br>(xii) To solve a homogeneous differential equation of the type dy\/dx = F (x, y), we make substitution y = vx and to solve a homogeneous differential equation of the type dx\/dy = G (x, y), we make substitution x = vy.<br>(xiii) A differential equation of the form dy\/dx + Py = Q, where P and Q are constants or functions of x only is known as a first order linear differential equation. Solution of such a differential equation is given by&nbsp;<img decoding=\"async\" src=\"https:\/\/www.indcareer.com\/schools\/wp-content\/uploads\/2024\/05\/49063629921_39c06a8f22_o.png\">&nbsp;where I.F.
