SUMMARY

The discussion focuses on solving the differential equation dy/dx = (y^2 - 1)/x. Participants are tasked with deriving the general solution and verifying that the straight lines y=1 and y=-1 satisfy the equation. The integral approach involves rewriting the equation as dy/(y^2-1) = xdx, which leads to the integration process necessary for finding the general solution. The verification of the straight lines as solutions is confirmed through differentiation.

How to do this integral?

dy/dx = (y^2 - 1)/x

a) Give the general equation of the curves that satisfy this equation

b) Show that the straight lines y=1 and y=-1 are also solutions.

Thank you!
 
Physics news on Phys.org
dy/(y^2-1)=xdx
Proceed from there (integrate).
 
b) what is the derivative of a straight line? is it equal to what the diff eq tells you about it?
