I want to believe that there are real mathematicians in
this group. So I wanna share my recent exam questions with
them nd see who can solve it!!!

Re: Nairaland Mathematics Clinic by Olarewajub: 8:03am On Feb 25, 2017 |
Please i need assistance with interpretation of this question. A point A and B divide the line joining P (3,2) and Q (7,9),internally and externally in the ratio of 5:4 respectively. Find the coordinates of A and B. Will i be right if i say m=5 and n=4? |

Hi all. Please what's the easiest way to find the value of the angle A in the equation below (without using trial and error method) tanA - sinA = 0.083 Cc teempakguy profmathsland mathefaro thankyoujesus and all maths guru |
Re: Nairaland Mathematics Clinic by Nobody: 12:17pm On Feb 25, 2017 |
Olarewajub: I think they meant A divides internally in the ratio of 5:4 and B divides externally in the ratio of 5:4. So solve for the coordinates of A and B separately using the same ratio. |

quitereal6: Half angle formula |

Suppose that f(x) = 1/x+1 and g(x) = 4/x+1. Find the domain of each of the composition a) f o g b) f o f |

dyshow:your questions are not clear |

3raise to power of 2x=8x find x |
Re: Nairaland Mathematics Clinic by naturalwaves: 12:52am On Mar 06, 2017 |
Bennystrings:The domain of f(x) is all real numbers EXCEPT -1 The domain of g(x) is all real numbers EXCEPT -1 a) f o g implies f(g(x) = f(4 /x+1) Recall that f(x)= 1/ x+1. what this means in simple terms is that f of anything, is 1/ ( that thing +1) Therefore, f( 4/ x+1) = 1/ ( 4/ (x+1) + 1). This will finally give (x+1) / (5+ x) as the final answer. b) f o f? First time I am seeing this kind but if the question does not have an error, then f of = f( f(x) = f ( 1/ (x+1)) = 1/ (1/ (x+1) + 1) = (x+1)/ (2+x). Would have taken a snap shot of the solutions but my phones have been stolen. Had to manage to type it out. cheers! 1 Like |

Question 3.

Re: Nairaland Mathematics Clinic by naturalwaves: 4:33pm On Mar 06, 2017 |
Hadampson:If you use an android phone, just expand the screen, you will see the solutions clearly.The phone I used was not too good and it cannot be typed . I got 2 set of solutions but only one set is correct . The final set of answers is Constant ratio = 2 First term = 5 Sum of first 20 terms = 5242875. |
