AkinPhysicist:if the answer was meant to be a decimal, the counting method would fail. That is exactly why the ITERATION method was introduced as. Avalid mathematical method for "Counting". The only difference is that it counts by itself until it gets to the actual answer and it stops. The iteration method is not just any "creative" solution either, it was developed using the Fibonacci sequence. Now, here is what would work ; Go on your calculator and type : 0+1= Ans Now, type : (15*Ans) - √(Ans(Ans+15)) = Now keep pressing the "=" key until the answer stops changing. It will stay as 49. That is iteration. Again that doesn't tell you if there are other solutions. So to find all other solutions, you need to find out the first derivative, equate to zero, fond its roots, and the iteration process in another direction Way from the first. 5 Likes 1 Share |

Hellooooooooo!!!! 30 minutes left o. Atleast just tell us what x is. Then let your proof come in later. 0 ÷ 0 = x, Find x Prize : #15k |

For #15K, I need someone to mathematically find x if 0 ÷ 0 = x Using mathematical methods pls. |

FisifunKododada: Okay i get it. You guys want me to be creative but I'm being rigid. First, maths is not an ART, it's a SCIENCE. Unless you re talking quantitative aptitude (I keep trying to make a distinction between both) If you know how many years I have been in the game, well, let's just say, wait until you have a PhD, then you can begin to understand why 'creativity" must also be very robust and guided. When one prof comes and punctures your steps, you'd be left gasping for breath. As for the other guy being too clever, well... Remember I asked for us to do a competition. Fine, he should try me. Drop a question I cannot solve, and after 30 minutes, he must post the solution. Mind you, I'm not into riddles or quantitative reasoning (unlike the OP). Challenge me with high level mathematical proofs please. 1 Like |

AkinPhysicist:if you are looking for fun, get a girlfriend..I'm not GAYbriel. Also, it's not grammar, it's a mathematical term for the validity of a mathematical method. That test is performed on all so-called mathematical steps (or methods) to scream out "wuru wuru to the answer" kind of solution. I'm sure you heard about one Nigerian Dr who solved an age long mathematical hypothesis..He was able to prove it. His method was subjected to many mathematical tests for validity and so on. Do you think your method would even be acceptable?? Well maybe to your NL pack of followers...But not to higher minds. 1 Like 1 Share |

kelvinreality:well, if you insist ooo He was only doing trial and error. So if a= √x And b = √(x+15) Then we want a+b =15 So the trial and error method he did was to say let a and b = 1 and 14 , 2 and 13, 3 and 12.......7 and 8 Then for each of those guesses (which of course will not be listable if the question had say, 99 instead of 15) he said; If x = a squared So let's see if b = √ (x + 15) ( using that same x we just got) will give us the number we want b to be. (As earlier listed out) So he looked at all those whole numbers..Lol...Before arriving at x = 7 squared = 49 And b = √(49 + 15) = 8 which is the same as what we paired up. Now do you get it? Disclaimer...This method (as mathematicians will say) does not provide all possible solutions for x and hence, fails the "reductio ad absurdum" test. 3 Likes |

AkinPhysicist:yes but like i said earlier... while you are still solving maths by "counting" (hahha ha hhahaha), your counterparts abroad (or your seniors abroad - if we are talking about me) are using the considering real numbers, complex numbers and in case you have not heard of the latest one, 3D numbers, to solve problems. So let's try to step up the game..Okay? I was going to give you some 3D angle trig questions...But it's okay you can go and play bball. Lol |

kelvinreality:ignore that method, sometimes, the answer may be a decimal...He is just doing what we used to call "wuru wuru to the answer" Because he now knows the answer |

AkinPhysicist: You disappointed me walahi So this is maths....Hahhahaha....Aye mi temi bami... You will end up in McDonald's!!!! Ahhhh. Okay, sit down my dear, let me tell you the mistakes you make. Maths is logic, it's not trial and error, in maths we ensure all stones are uncovered. What if the problem has more than one solution?? What you do not understand is that quantitative reasoning is NOT maths. This isn't how we engineers build robust systems. If maths were done this way, planes and rockets will crashland like butterflies. You need to make sure all possible domains and ranges are considered. Now, what if I told you that this question has more than one answer? 49 is just one of them. There you have it, but I understand you may not have a science background so you may not realise what I mean. Perhaps in commerce, numbers have to always be simple integers. Lol @ICAN maths sha. Lol...You are so funny. 4 Likes |

AkinPhysicist: Running away from tough questions my boy?? Next time, be humble cos not everyone on NL is your mate. Ordinary trigonometric differentiation, the ICAN student cannot attempt. I expected you to atleast tell me what steps you could take to normalize the problem, particularly by geometrical representation, but alas! We can all see. My advice for you is to get a solid maths textbook that challenges you, not those quantitative aptitude that you or the OP will be bringing on here for N 10,000 reward. 1 Like |

AkinPhysicist: Lol, Matlab at last isn't it. Of course another solution that doesn't involve squaring both sides is the use of ITERATION. NOW, here is your assignment, post a solution that does not involve numerical, graphical or algebraic analysis. Not also involving the use of geometrical representation. |

YungMillionaire:lol....Matlab you say. That's why i expected you to drop the answer i. 3 minutes. I judged wrong. Well you now have spent 3 hours or so on it..What happened to your Matlab? Lol. You better sit down and learn. X = 49 Take √(x) from both sides. Square both sides Collect like terms, That linearises the problem. Solve for x. Q.E.D Now, next question. Y = arcsin(x+x^2) + arccos(xy) Find dy/dx |

Some people claim to be maths gurus when. All they know is QUANTITATIVE APTITUDE Some of us have finished courses and degrees in real analysis, abstract analysis, numerical analysis, applied maths and why have you.

melodyogonna:you have problems too. Source needs to be stated. How is he listening to the live program? NTA? CHANNELS TV? AIT? Radio Nigeria? Facebook live? Any web link? These are called sources. A source is any entity that could be tendered legally as an authorized information channel. This will never make front-page without the OP naming a valid source of his information. Even if he were present at the church service, he needs to have a valid source (in this case, an authorized report or video/audio evidence) that could be tendered anytime a case of libel comes up. You need to learn how to reply people as not everyone here is of your ignorance cadre. |
