to make it clearer rewrite the equation as and put
ok i dont see how the book came up with the substitution of u= y^-1
so here is the problem..
(t^2)dy/dt + y^2 = ty
my question is this, if u = y^(1-n) wouldnt n = 0?
i think the book may have made a mistake on this problem....can someone please check the problem and see if the substitution is correct? thanks in advance..
