Derivatives of a higher order - Satisfying the equation

Click For Summary
SUMMARY

The discussion focuses on demonstrating that the function y = x * e^x satisfies the second-order linear differential equation A(d²y)/dx² + B(dy/dx) + Cy = 0 for specific constants A, B, and C. Participants identify a mistake in calculating the derivative dv/dx, which is crucial for determining the values of A, B, and C. The conversation emphasizes the importance of accurate differentiation in solving differential equations.

PREREQUISITES
  • Understanding of differential equations, specifically second-order linear equations.
  • Proficiency in calculus, particularly in differentiation techniques.
  • Familiarity with exponential functions and their derivatives.
  • Knowledge of solving for constants in differential equations.
NEXT STEPS
  • Review the method of solving second-order linear differential equations.
  • Practice differentiation of products and exponential functions using the product rule.
  • Explore the role of constants in differential equations and how to determine their values.
  • Learn about the application of the characteristic equation in solving linear differential equations.
USEFUL FOR

Students studying calculus and differential equations, educators teaching these concepts, and anyone looking to improve their problem-solving skills in higher-order derivatives.

Homework Statement



Show that y= xex satisfi es

A(d2y)/dx2 + B(dy/dx) + Cy = 0

for suitably chosen values of the constants A, B, and C.

Homework Equations



Y=xex

The Attempt at a Solution



Please see the attachment. I get to a point where I need to find the value of A, B and C but cannot as I'm dealing with x2 terms.

Help would be much appreciated.

You calculated dv/dx wrong.
 
Could you explain Where I went wrong?
 
Oh, I see the mistake, Thanks
