yup, what i mean is an "integrating factor"..so we only no need to consider the integrating factor when the differential equation is in separable form huh?thanks mates..really2 thanks
i will come out with my final solution for question 1 first (still need a help in question 2 afterwards)
p/s: you are a lecturer or tutor maybe huh? sorry for off topic
Hye again..thanks again for all your instruction, im done with no 1..now it is no 2 question
after differentiate with respect to x i obtain
thus,how can i get the characteristic equation (as the initial step of using variation of parameter method) from that equation since got two variables which is x and y;
anybody help??thanks in advance
i thought is it we need to separate those x??
