Let me get this right.do you suggest that i divide d(x,y)<= d(x,z)+d(z,y) by 1+d1(x,y) in order to reach an inequality that is true?or do you suggest dividing d1(x,y)<= d1(x,z)+d1(z,y) by 1+d1(x,y) in order to reach d(x,y)<= d(x,z)+d(z,y)?

Homework Statement the actual problem is to show that d(x,y)=d1(x,y)/[1+d1(x,y)] expresses a distance in R^n if d1(x,y) is a distance in R^n.Based on theory I have to show that i) d(x,y)>=0 , ii)d(x,y)=d(y,x) and iii)d(x,y)<= d(x,z)+d(z,y) i've proven the first two so basically how can i...

ok so it's a linear partial differential equation...i'll try some ways out and if I still can't solve it i'll let you know:)

well i initially thought about integration...but really i have no clue about it since i haven't be teached yet how to solve nonlinear differential equations(at least that's what I think this equation is,correct me if I'm wrong)

well i have been trying to solve this equation and i just can't... the solution is given and it's at the second pdf file but i can't understand the procedure can somebody please help?
