# Help me impress my lecturer

1. He gave everyone a really hard differential equation to solve which noone could do in the first lecture
Can someone solve it for me: x*(dy/dx) + y = 1
2. You're gonna take all the credit from someone else's work aren't you

I'll give you a clue: where is a very simple function of and that you need to find.

Okay sorry, possibly wasn't the clearest way of saying it! I'm assuming that you've done implicit differentiation because if you haven't, you probably won't be able to work this out. What's I'm trying to say is that there is a function that, when you differentiate it, you get the left hand side of your equation. Which then makes it extremely easy to solve. The tricky bit is working out what the function is and you should be able to work it out if you know how to do implicit differentiation.

Not at all hard! Divide through by x and find the PI which should be .
Spoiler:

But the general solution is . NOW GO IMPRESS UR LECTURER M8

wtf is A?
10. ....and why would ur lecturer be impressed by this?

wtf is A?
m8 I arrived here to give you an answer, NOT a lesson. A is any constant. You need a certain condition if you want it to be a number

a class of like 80 people couldnt do it
If i was the only one who could id be cool
13. Bake him a cake.

I'm surprised as well. I bet he's doing a foundation maths course (or something mathsy) at a uni and he's on his first year, because this is a very simple problem indeed which pops up as the first thing in one of the Further Maths A-Level modules lol

Nope doing pure maths, recieved a B for a level matsh( which isnt great but I did get 4 As in my modules) did not do further maths
Plus I haven't touched maths for over 3 months
