Could someone help me with this locus question? "Find the equation of the locus of the midpoints of all chords of length 4 units of the circle with the equation x^2+y^2-4x+2y=4 I'm just completely lost about how to tackle this question (I only heard something called loci existed like, 12...

Thank god for whoever created wolfram alpha

Emma :\

My daily study regime now consists of maths and that's about it. Like, the only stuff I do for my other subjects is reading my English text until I fall asleep

Comfortingly busy

hahahahahahahahahahahahahaha OMG WHY AM I THE ONLY ONE

Heck, I might turn up to year 12 subject selections semi suicidal and pick both 4U English and maths It's certainly something's that's entered my mind before (doing both extensions, that is)

What happened to your staunch opposition to the subject?

I think you made a mistake taking the -3 out (look at the + and - signs), but you're on the right track! You can divide the 3 out (divide 3 from both sides, and 0/3 = 0 so the RHS doesn't change) and then you get a simple quadratic inequality (not sure what it's called) (remember, since you...

Hmm, I think you might have made a mistake factorising Remember, -3p^2-6p+9<0 can be simplified into a much more workable inequality

Consider the definition of "positive definite" in regard to the leading coefficient and the discriminant and then try to solve it from there :)

Yay! Guess I won't be the only person doing Japanese anymore :D

I literally just broke down after spending an hour doing a maths question before realising the question asked you to prove not solve -.-

I've always wondered what it would be like to learn maths for the sake of learning, free from any worries about exams and scaling since my enjoyment of maths is directly proportional to how well I do in it.

Oh Justem <3 I'd give you rep if I knew how

Thanks :) I'm still very enthusiastic about school, but everything feels so... surreal. The workload is much bigger as well. I've never had to give in homework the day after it was given :\

Omg thanks for the rep :D Another question, How much "rep" constitutes one bar?

I feel so indifferent to my subjects right now. Like, I still haven't had the time to think about them since the thing that's mostly going through my mind is "holy shit I'm in year 11".

This might sound very stupid but... what is rep?

Not related to school, but what are the green bars under everyone's name and why do some people have red bars?
