Math Advanced Math Fundamentals of Differential Equations (9th Edition)

Whether the differential equation ( y e − 2 x + y 3 ) d x − e − 2 x d y = 0 is homogeneous, Bernoulli, linear coefficients, or of the form y ′ = G ( a x + b y ) . The differential equation ( y e − 2 x + y 3 ) d x − e − 2 x d y = 0 can be identified as Bernoulli _ . Definition used: Homogeneous equation: “If the right-hand side of the equation d y d x = f ( x , y ) can be expressed as a function of the ratio y x alone, then we say the equation is homogeneous.” Bernoulli equation: “A first-order equation that can be written in the form d y d x + P ( x ) y = Q ( x ) y n , where P ( x ) and Q ( x ) are continuous on an interval ( a , b ) and n is a real number, is called a Bernoulli equation.” Equations of the form d y d x = G ( a x + b y ) : “When the right hand side of the equation d y d x = f ( x , y ) can be expressed as a function of the combination a x + b y , where a and b are constants, that is, d y d x = G ( a x + b y ) .” Linear coefficients: “The equations of the form ( a 1 x + b 1 y + c 1 ) d x + ( a 2 x + b 2 y + c 2 d y ) = 0 , where a i 's, b i 's, and c i 's are constants. If a 1 b 2 ≠ a 2 b 1 and b 1 ≠ a 2 , seek a translation of axes of the form x = u + h and y = v + k , where h and k satisfy a 1 h + b 1 k + c 1 = 0 , and a 2 h + b 2 k + c 2 = 0 .” Calculation: The differential equation is, ( y e − 2 x + y 3 ) d x − e − 2 x d y = 0 Rewrite the equation d y d x + y x = x 3 y 2 as shown below. ( y e − 2 x + y 3 ) d x − e − 2 x d y = 0 − e − 2 x d y = − ( y e − 2 x + y 3 ) d x d y d x = y e − 2 x e − 2 x + y 3 e − 2 x ... ( 1 ) d y d x − y = e 2 x y 3 Clearly, the equation is of the form d y d x + P ( x ) y = Q ( x ) y n . This is a Bernoulli equation with n = 3 , P ( x ) = − 1 and Q ( x ) = e 2 x . Note that, the right hand side of the equation (1) cannot be expressed as a function of the ratio y x alone and a function of the combination a x + b y . Thus, the equation cannot be identified as homogenous and d y d x = G ( a x + b y ) . By the definition stated above, the equation cannot be identified as Linear coefficients. Therefore, the equation ( y e − 2 x + y 3 ) d x − e − 2 x d y = 0 can be identified as Bernoulli _ .

( 1 ) d y d x − y = e 2 x y 3 Clearly, the equation is of the form d y d x + P ( x ) y = Q ( x ) y n . This is a Bernoulli equation with n = 3 , P ( x ) = − 1 and Q ( x ) = e 2 x .
