1.) xy dx + e^(-x^2)dy=0 ; y(o)=1 i got that problem down to 1/2 e^(-x^2) = 1/2(y^2) - lny but i don't know how to solve that for y thanks!!

Hello, holly123! You've made an error somewhere . . . Separate variables: . . Integrate: . .[1] . . Since Then [1] becomes: . Therefore: .
oh im sorry i wrote it wrong! it's xy dx + e^(-x^2) (y^2-1) dy=0 sorry im confused on how to use the symbols and write this all out correctly and i completely forgot to add the (y^2 -1)
