Mathemagician1:pls can anyone recommend w textbook that explains Gaussian elimination method n echelon row form and pls wat form will the result of a 2x2 multiplied by a 3x3 matrix give? waiting in anticipation |
Re: Nairaland Mathematics Clinic by Mathemagician1(m): 7:25am On Dec 13, 2015 |
Idrhas: I'll recommend College Algebra by Frisk and Hughes if you're a newbie to the topic and Engineering Mathematics by K.A Stroud if you've been introduced to the topic but need a little extra push. The product of a 2 x 2 and 3 x 3 matrix will be an inconsistent system, that is, the product doesn't exist because the number of columns in the first system is not equal to the number of rows in the second system. For a product AB of two matrices to exist, the number of columns of A must equal the number of rows of B. If the product exist, it will have as many rows as A and as many columns as B. Hope this helps. |

dprinz99:Pure mathematics by Bundey Additional Mathematics by Godman Project mathematics 1-3(dis one is very elementary bt i dont think its in pdf format aspa ritten by a nigerian) Lastly Engineering mathematics(green cover) still d best elementary for A-levels |

Idrhas:. It is best you go for the schaums outline series on linear algebra because it gives a blow-by-blow account of each topic.All topics are self I explanatory.This book is a guide to d solid foundation that can be of help in probably all areas of maths. |

At 6:00 am, a freight train passes through Sagebrush Junction heading west at 40 miles per hour. At 8:00 am, a passenger train passes through the junction heading south at 60 miles per hour. At what time of the day, correct to the nearest minute, will the two trains be 180 miles apart? |

Two airplane A &B left the same airport 'A left at 9am flyin due east n B left at 9:10am flyin due north. A's speed is 250km/h and B's speed is 180km/h. how far are they frm each other at 10? give anxa to 1 dp |

Madmathecian:at a particular time t ta consdering tha the vo'ociyis the cgage doen not chang thoughou thjouney the train moving at 40miles/hr would have a distance of 40(t-6). AT the same time t the train moving with velocity 60miles/hr would have moved a distance of 60(t-. the south and west are at angle of 90 degrees, the hyponuse of that right angled triangle would be 180 miles. (40(t-6))^2+(60(t-)^2=180 solve for t |

Sirneij: For n = 1 1(1+1)(1+2) = 6 For n = 2 2(2+1)(2+2) = 24 Assuming n(n+1)(n+2) is a multiple of 6. For induction, for n+1 (n+1)(n+2)(n+3) n(n+1)(n+2) + 3(n+1)(n+2) ................... (i) This is divisible by 6 Note that (n+1)(n+2) is always divisble by 2 (even). Therefore 3(n+1)(n+2) is always divisible by 6 for n € Q+ Therefore equation (i) is always divisible by 6 for n € Q+ Therefore n(n+1)(n+2) is a multiple of 6 for all positive integers.

Sirneij: For n = 1 (1)4 + 4*(1)2 + 11 = 16 For n = 3 (3)4 + 4*(3)2 + 11 = 128 Assuming n4 + 4n2 + 11 is a multiple of 16. For induction, we use n+2 (n+2)4 + 4(n+2)2 + 11 ...............................(i) Expanding n4 + 8n3 + 24n2 + 32n +16 + 4n2 + 16n + 16 + 11 n4 + 4n2 + 11 + 8n3 + 24n2 + 48n + 32 n4 + 4n2 + 11 + 8(n3 + 3n2 + 6n + 4) n4 + 4n2 + 11 + 8(n+1)(n2 + 2n + 4) Now consider 8(n+1)(n2 + 2n + 4) Since n is odd, (n+1) is always a multiple of 2 (even) Therefore 8(n+1) is a multiple of 16. Therefore 8(n+1)(n2 + 2n + 4) is a multiple of 16. Therefore equation (i) is divisible by 16 for all odd positive integers. Therefore, n4 + 4n2 + 11 is a multiple of 16 for all odd positive integers Gracias, Good Morning Nigeria. #GodBlessNigeria |
