WebsiteDesigner: @Richiez, pls can u solve a Von Smoluchowski equation. Let me know if u can. |
Re: Nairaland Mathematics Clinic by agog: 10:19am On Jan 03, 2013 |
Richiez: I give it to you fair and square. You inspire me! |
Re: Nairaland Mathematics Clinic by Ehinafe: 10:21am On Jan 03, 2013 |
Richiez: nice try bro, although you made some some mistakes especially at the point where you took log of both sides. e.g it ought to be log(x+y)= log5 and not logx + logy = log5. but i must admit, you did a very good job. here's another approach; x + y = 5.......(1) x^x + y^y =31.......(2) from eqn(1), x=5-y, hence we substitute this value for x in eqn(2). (5-y)^(5-y) + y^y = 31.......(3) now, we have reduced the problem to what value of y that must be inserted in eqn (3) to obtain 31. a thorough look at eqns (1) & (2) shows that the values of x & y must be positive integers within the range 0<x<5 and 0<y<5 clearly, y=3 i.e (5-3)^(5-3) + 3^3 2^2 + 27 4+27=31 now that we have established that y=3, we shall substitute the value of y in eqn(1) to get x recall that x+y=5 therefore; x+3=5 or x=5-3=2 hence, x=2 when y=3 Richiez, how good are you in solving Dynamic Programming mathematical algorithm? I need to know because I have one here that I am not sure you can get the answer right. |

Mathematics is my favorite subject anytime anyday. And i had good grade in courses that has to do with mathematics in the university. Drop any question my way let me destroy it. 3 Likes |

olasesi:the answer obeyed the equation. X+y=5 2+3=5. X^x+y^y=31 2^2+3^3=31 (equation proved) |

Richiez, I really must commend your effort, you are good.. I've got this questions on Metric Spaces and I will really appreciate if you give a thorough breakdown. 1. If d1 and d2 are metrics of X, is it true that d1 + d2, d1 - d2, d1 * d2 are metrics of X ? I just need to grasp the basic concept. 2. We say that two metrics d and d' are equivalent on X if a convergent sequence in (X,d) is a convergent in (X, d') and vice versa.. Given a metric d of X, prove that there exist a metric d' equivalent to d and bounded by 1. 3. Suppose dn is a sequence of metric of X. Show that there exists a metric bounded by 1, such that the convergence sequence in (X,d) is convergent in each (X,dn) This is under topology, I will appreciate if you can attempt or give a clue to these questions. |

olasesi:yes you are correct. My bad. I tried solving it by loging the x and y individually,and it was wrong. Log(x+y)=correct. 1 Like |

x+y=5..........(eqn 1) .......means that .....the summation of x and y is equal to 5...... Bracket in mathematics is used to group expressions......giving it the idea of a single number E.g (ABC)D=19.......this means that the product of A,B and C gives a number in that bracket whose product with D then gives 19 even though the product can be made in any other I.e product is associative....that is exactly what the example means..... (x+y)=5.....(eqn 2) means that the summation of x and y gives a number in that bracket which is equal to 5........ Therefore equation 1 is the same as equation 2 The bracket is not just written as the summation is between two numbers and a bracket in this case would appear redundant...... 2 Likes |

Ehinafe: Richiez:dynamic and programming mathematical algorithm are for those studying mathematics as a course on it own. Though,it's very intriguing,and looks superior to the logarithmic method. |

Lol. All I have seen here is some very pithy attempts at mathematics, in fact bordering on simple arithmetic. Let's have some hard-core simulation and pursuit theory. |

Solomon111, you are quite correct, but you should realize that dynamic programming and Non-linear programme are better-suited to real-life situation than all other mathematical models |
