m coming bk to solve some of ur Questions.. Pending the time.. There is a mistake in ur Question one.. It shld be like this Simplify (x2 - 1)/(x3 -2x2 - x + 2) tobillionaire: |

dejt4u: yea man you're right .... here ------$01u10n from down *) Given |2x-3|=13 which => +/- (2x-3)=13 i.e 2x-3=13 , => 2x=16. => x=8 or -(2x-3)=13 , => -2x+3=13 , => -2x=10 , => x=-5 hence we have (-5 , 8 ) as solution set . *) y= 3x^2 -x^2 +x we compute integral for 1<x<3 => $(3x^2 -2x+1)dx = x^3 -x^2 +x for 1<x<3 now for F(x)=x^2 -x^2 +x we compute F(b)-F(a) (where a=1 , b=3) so that => [(3^3 -3^2 +3)-(1^3 -1^2 +1)] = 21-1= 20 *) dy/dx = 4x-3 , computing 'y' at (2,5) , we take integral on both sides => y=$(4x-3)dx = 4x^2 -3x +K y=2x^2 -3x +k , now at (2,5) . for x=2. , y=5 => 5=2(2)^2 -3(2) +k => 5=2+k , thus k= 3 hence we have. y= 2x^2 -3x +3 *) For two perpendicular lines , m1*m2=-1 equation of PQ = x-2y+4=0 or y= x/2 +2 , so that m1 =1/2 => m2/2=-1. or m2=-2 now , by definition, m=(y-y1)/(x-x2) or y-y1=m(x-x1) Given PQ's coordinate as (1 ,-1) ..I.e x1=1 , y1=-1 thus we have y-(-1)= -2(x-1) or y+1=-2x+2 or 2x+y-1=0 *) Given two angles 44° & 112° known that sum of angles in a triangle gives 180° thus let's call the third angle @ => @+44+112=180 => @= 180-156=24° since its a bisector , => 24/2=12 ° *) by testing a.b=a+b-ab. . is commutative . *) option D (wait for solution from my boss.) |

Re: Nairaland Mathematics Clinic by dejt4u(m): 8:28am On Jun 24, 2015 |
tobillionaire:the correct question is; Simplify (x2 - 1)/(x3 - 2x2 - x + 2) Solution: (x2 - 1)/(x3 - 2x2 - x + 2) = (x2 - 12)/(x - 1)(x + 1)(x - 2), !diff. of 2squares will be applied to the numerator while I factorize the denumerator(Long division cn be used after getting one factor) =(x - 1)(x + 1)/(x - 1)(x + 1)(x - 2), = 1/(x -2) Option D |

The correct answer to Question 2 is 192, i.e. 72 + 120. |

Pls help with dis question...FIND the root of the equation if x^3-x-1=0 using bisection method, let epsulum =0.001 |
Re: Nairaland Mathematics Clinic by frob0genius(f): 3:25pm On Jun 25, 2015 |
Profmaojo: Firstly, you need to find two points say a and b such that if you put a or b in f(x) either f(a) or f(b) would give you opposite signs i.e either f(a) can be negative or f(b). But they can't have the same sign. Let the interval be [1,2]. This implies that a=1 f(a) =-1 b=2 f(b) =5 Next find xo which is (1+2)/2=1.5 F(xo) =0.875 Since your f(a) * f(xo) <0 your new interval is [1,1.5] Continue your iteration until your error =0.001 |

Pls ma i didn't get d answer , can u help me to complete it pls frob0genius: |
Re: Nairaland Mathematics Clinic by frob0genius(f): 7:58pm On Jun 25, 2015 |
Profmaojo: I didn't get the answer, I just started it. Do you know how to use bisection method? Something like this. But you continue iterating until the absolute value of your f(xn) minus f(xn-1) is less than or equal to epsilon 2 Shares
