 Apr 7 comment Is limits $\lim_{x\to\infty}{(x-2)^2\over2x+1}=\dfrac{1}{2}$? @DanielFischer are you going to write it as an answer? Apr 7 comment Is limits $\lim_{x\to\infty}{(x-2)^2\over2x+1}=\dfrac{1}{2}$? What do you mean? I divided both numerator and dneominator by x Apr 3 comment Solve this simple polynomial @RecklessReckoner Thank you so much, I'll look into synthetic division! Apr 3 comment Solve this simple polynomial @RecklessReckoner So how do you come up with $(x^2+x+1)$? Apr 3 comment Solve this simple polynomial What do you mean by long division? Do you mean $x^3-x^2-x-2 \over (x-2)$ Apr 3 comment Solve this simple polynomial @MichaelHardy My brain is extremely fuzzy right now it's 2 am lol --cramming for exam Apr 3 comment Solve this simple polynomial I don't get it. How can you know x-2 is a factor? And if you know it's a factor, how can you come up with x^2+x+1 Apr 3 comment Solve this simple polynomial The limit problem holds little relevance to the question Apr 3 comment Solve this simple polynomial It is clear, I'm only trying to figure out how I can factor out the problem so that I could obtain x-2 Apr 3 comment Solve this simple polynomial @IanColey well, if I got (x-2). I could eliminate them. I'm trying to solve a limit problem Mar 3 comment Is a function still a function if it doesn't have any rule? Ok then never mind the sources, a consensus has been reached. A function it is then. Can someone write the answer? Mar 3 comment Is a function still a function if it doesn't have any rule? @ploosu2 for example: f(x)=3+2x. I don't know whether or not it's called a rule though lol Mar 3 comment Is a function still a function if it doesn't have any rule? @Emin Why? Can you cite any source? Feb 24 comment Simple function question Is this allowed? Take a look my updated question, tell me what you think. Feb 24 comment Simple function question @DavidMitra I've updated the question, take a look. What do you think? I need the answer algebraically Feb 24 comment Simple function question @DavidMitra your comment might be the solution.. Mind explaining it as an answer? I'm a noob in functions. Nov 19 comment Math behind Keynesian Expenditure Multiplier Cool, thanks :) Nov 19 comment Math behind Keynesian Expenditure Multiplier So, it's just a well known geometric series then? What is the geometric series called? Ah, and would you mind giving me a link to more of these well known geometric series? Nov 19 comment Math behind Keynesian Expenditure Multiplier @hejseb is there any other thing ambiguous in my question? Nov 19 comment Math behind Keynesian Expenditure Multiplier ah sorry lol, MPS equals to 1 - MPC
