What is the difference and similarity between a 3.7 and a 3.70? |
| Re: For Mathematicians Only! by samolina1(m): 8:43am On Mar 28, 2011 |
No difference but the same variable. |
| Re: For Mathematicians Only! by Nobody: 9:25am On Mar 28, 2011 |
^olodo. . . The diff is dat one has '0' at d back while d other doesn't! |

As an 100 level student in OAU,d different btw 3.7 and 3.70 are :- 1. 3.7 is in 2 s.f while 3.70 is in 3 s.f. 2. 3.7 is in 1dp while 3.70 is in 2 dp. |

Analytically speaking, both numbers are the say since they occupy the same position on the real line (Real analysis) |

What does this question has to do with OAU? Some ppl's mentality sef |
| Re: For Mathematicians Only! by shomatth(m): 5:36pm On Mar 28, 2011 |
stevetboy dis question need neither abuse nor analysis, but mathematical answer of which i did. don't change topic about oau. |

Who will explain Demovire's theorem for me? Shomath from OAU, will u help out? |
| Re: For Mathematicians Only! by Odunharry(m): 6:55pm On Mar 28, 2011 |
easy |

How is this question relevant to anyone? |
| Re: For Mathematicians Only! by Nobody: 9:29am On Mar 29, 2011 |
As a physicist. D diffe between both figure is +or- 0.5. I.e the range of both is(3.65-3.74) which simply means 3.70 |

Harbijoye, be explicit! Demovire's theorem, anybody? |
| Re: For Mathematicians Only! by mufuteeeee(m): 8:47am On Mar 30, 2011 |
check http://en.wikipedia.org/wiki/De_Moivre%27s_formula. Everything is there. Or tell me if U want more explanations. |
| Re: For Mathematicians Only! by Nobody: 11:31am On Mar 30, 2011 |
I want more explanation |
| Re: For Mathematicians Only! by mufuteeeee(m): 4:10pm On Mar 31, 2011 |
e^(iθ)=cosθ+i(sinθ) [Euler's formula] therefore: e^(inθ)=[cosθ+i(sinθ)]^n=cos(nθ)+isin(nθ) from law of exponents. The first identity comes from expanding e^x=1 +x+ x2/2!+ x3/3! +x4/4! +x5/5! +xn/n! and replacing x with iθ. I think this should help |
