Can someone explain to me ow i missed this great thread?! |

@ benbuks, is that your picture? |
Re: Nairaland Mathematics Clinic by Nobody: 9:09pm On Aug 02, 2014 |
smurfy: @ benbuks, is that your picture? yes boss , surprised .? whose do you expect ..? |
Re: Nairaland Mathematics Clinic by Nobody: 10:40pm On Aug 02, 2014 |
benbuks: Nice boy! I've always known you were a good 'boy'. I want you to know that I like your person very much. That's the truth. |

smurfy: haha..tnx boss .. Na God. oo. |

benbuks:Boss, I dey fine o. |
Re: Nairaland Mathematics Clinic by Nobody: 10:42am On Aug 04, 2014 |
benbuks: use first principle differentiate x1/3 guys kindly give this a try plzzz |

Please help me prove that Log(1+2+3)= Log 1+ Log2+ Log3 I did it by opening the bracket to get exactly what is at the right side but was told t'was wrong. |
Re: Nairaland Mathematics Clinic by dejt4u(m): 2:17pm On Aug 04, 2014 |
Allenkee: Please help me prove thatLHS: Log(1+2+3) =Log(6) RHS: Log 1+ Log2+ Log3= log(1x2x3)=log(6), therefore, LHS=RHS...proved |
Re: Nairaland Mathematics Clinic by efficiencie(m): 8:00pm On Aug 04, 2014 |
dejt4u: If i get your theory right: log[x(1)+x(2)+x(3)+...+x(n)]=logx(1) + logx(2) + logx(3) + ... + logx(n) then why is it that: log10=log[1+2+3+4]=log1 + log2 + log3 + log4 = log(1x2x3x4)=log(24) hence log10=log24 which is a great contradiction!!! 1 Like |
Re: Nairaland Mathematics Clinic by Nobody: 8:36pm On Aug 04, 2014 |
Log (1+2+3) is equal to log 6... also, log 1 plus log 2 plus log3 is equal to log(1X2X3) which is also log6.... He talked abt proving for the first 3 terms only... |
Re: Nairaland Mathematics Clinic by dejt4u(m): 9:38pm On Aug 04, 2014 |
efficiencie:this is not a theorem.. We are all familiar with the basic laws of indices nd logarithm nd dis is none of them.. All the same, what i did is still very right and correct for that question nd for that condition.. If you look closely, u wil notice dat we dealt wit jst first 3terms i.e 1,2 and 3.. Thanks for dat observation my boss! |

Pls ooooo, cn someone make t the subject of the formula here? S=ut+1/2at. NB: It is not squared. It has no square. |
Re: Nairaland Mathematics Clinic by dejt4u(m): 7:51am On Aug 05, 2014 |
BestInDeeWorld: Pls ooooo, cn someone make t the subject of the formula here? S=ut+1/2at. NB: It is not squared. It has no square.this one na pry skul maths ooo.. t=2s/(2u+a).. If the last t is squared, t= 1/a (-u +/- sqrt(u2+2as)) |

1)¥(x2+ax-1)+¥(x2+bx-1)=¥a+¥b. 2)¥(2x+2+5)+¥(5.2x-9)=¥(3.2x+2+21). Find x. NB:Let ¥ rep. square root. |

Please, great maths men help out with this questions. 1. A man travels from Nigeria to Ghana by air and from Ghana to Liberia by ship. He returns by the same means. He has 6 airlines and 4 shippings to choose from. In how many ways can he make his journey without using the same airline or shipping line twice. ( further maths/2006/theory/13b) 2. (a) There are 6 points in a plane. How many triangles can be formed with the points? (b) A family of 6 is to be seated in row. In how many ways can this be done, if the father and the mother are not to sit together? (further maths/2006/theory/5) |
Re: Nairaland Mathematics Clinic by Arithmetic(m): 12:58pm On Aug 08, 2014 |
Drniyi4u:Yeah, correct. x=log25. What about the first one. |

Re: Nairaland Mathematics Clinic by Kendzyma(m): 3:23pm On Aug 08, 2014 |
Arithmetic: 1)¥(x2+ax-1)+¥(x2+bx-1)=¥a+¥b.rt(x^2+ax-1)+rt(x^2+bx-1)=rt(a)+rt(b) rt(x^2+ax-1)=rt(a) x^2+ax-1=a x^2+a(x-1)=1..........eq 1 rt(x^2+bx-1)=rt(b) x^2+bx-1=b x^2+b(x-1)=1........eq 2 dividing eq 1 by eq 2 1+a/b=1 a=0 ....subtituting a=0 in equation 1 x=+/-1 subtituting x=-1 in equation 2 b=0 subtituting x=1 in equation 2 b=0 hence b=a |

Kendzyma: rt(x^2+ax-1)+rt(x^2+bx-1)=rt(a)+rt(b) By comparing the terms, a is equal to b... Buh I don't see howw yu wud divide equation 1 by 2 to get that value... by mere looking at the equation, yu can deduce that X is 1... can yu expatiate how yu got 1 +a/b? |
Re: Nairaland Mathematics Clinic by Fetus(m): 7:30am On Aug 09, 2014 |
Plz guys kindly check dis...(1) test for the convergence of the series [^~ 1/(n+1)^3 dn.....where [=integral sign,^= upperlimit or superscript and ~=infinity symbol..tnx...(2)find the radius of curvature and the co-ordinates of the centre of curvature at the point x=4 on the curve whose equation is Y=x^2 + 5lnx - 24.... |
