AP EAMCET2013MathematicsDifferential Equations
The solution of the differential equation d y d x -2 y 2 x=e^x 2 x is
Options
- Ay 2 x=e^x+C
- By 2 x=e^x+C
- Cy=e^x 2 x+C
- Dy 2 x+e^x=C
Correct answer
B. y 2 x=e^x+C
Step-by-step solution
Given, differential equation is d y d x -2 y 2 x=e^x 2 x Here, P=2 2 x, Q=e^x 2 x aligned IF & =e^ -2 2 x d x & =e^ -2 2 x 2 & =e^ - 2 x & = 1 2 x aligned Required solution is aligned & y 2 x = e^x 1 2 x 2 x d x+C y 2 x & = e^x 1 d x+C & y 2 x=e^x+C aligned where, C is the constant of integration.
