randy17 Posted June 7, 2013 Share Posted June 7, 2013 (edited) 1. The problem statement, all variables and given/known datafind dy/dx for the function xy^2+xlnx=4y for x>o2. Relevant equationsxy^2+xlnx=4y3. The attempt at a solutionI found the dy/dx to be "(y^2+lnx+1)/(4-x)=dx/dy"What is it asking me to do with the x>0? Do they want me to plug in a value greater than 0 for x and solve for y? or what? Edited June 7, 2013 by randy17 Link to comment Share on other sites More sharing options...
daniton Posted June 7, 2013 Share Posted June 7, 2013 No,the function ln(x) is not defined for x<=0 Link to comment Share on other sites More sharing options...
