SUMMARY

The discussion focuses on finding the equation of a curve that passes through the point (1,3) and has a slope defined by the differential equation dy/dx = y/x^2. Participants confirm that integrating the equation is necessary to derive the curve's equation. The integration leads to the formulation of the solution, which involves substituting the constant using the given point (1,3) to find the specific curve.

PREREQUISITES
  • Understanding of ordinary differential equations (ODEs)
  • Knowledge of integration techniques
  • Familiarity with initial value problems
  • Basic concepts of slope and tangent lines in calculus
NEXT STEPS
  • Study the method of integrating separable differential equations
  • Learn about initial value problems and how to apply boundary conditions
  • Explore the implications of the solution to dy/dx = y/x^2 in real-world scenarios
  • Investigate the graphical representation of solutions to differential equations
USEFUL FOR

Students studying calculus, particularly those focusing on differential equations, as well as educators looking for examples of applying ODEs to find specific curves.

Homework Statement



Find the equation of the curve that passes through the point (1,3) and has a slope of y/x^2 at any point (x,y).

Homework Equations



Is there any general equation for the equation of the curve?


The Attempt at a Solution



the only problem in my homework I am stuck at, do you have to integrate y/x^2? I am quite confused as to how one could get the exact equation of this curve. any help would be appreciated
 
Physics news on Phys.org
y' = y/x^2

ODE

solve and sub for constant using codition point (1,3) lies on y=f(x)

Excellent suggestion.

Of course, this is dy/dx= y/x^2 which can be written as ydy= dx/x^2. Integrate both sides.
