tolulopevoice: Here. For part (c). You can use a calculator to approximate the answer to any degree of accuracy your calculator can offer. But I preper my answers expressed in arithmetical surds.

Pls who can solve this

Re: Nairaland Mathematics Clinic by Martinez39(m): 8:58am On Jul 30, 2019 |
toroabasietim94:ZERO. |
Re: Nairaland Mathematics Clinic by Nobody: 9:10am On Jul 30, 2019 |
Martinez39:show working |
Re: Nairaland Mathematics Clinic by Nobody: 3:20pm On Jul 30, 2019 |
toroabasietim94:The question becomes trivial once you see that the second equation is a sum of two cubes. |
Re: Nairaland Mathematics Clinic by Nobody: 6:43pm On Aug 02, 2019 |
Difficult but solvable.

Darivie04: 1. You cannot treat an infinite product as a series unless you take the logarithm and study it. 2. Also, in using D'Alembert ratio test, you cannot make any conclusion if the ratio is one in this case it's better to use Cauchy Condensation Test or Bertrand's test. 1 Like |

MathsEconomics:Lol, OK just felt like trying the question out using the basic math I know. |
Re: Nairaland Mathematics Clinic by Miracle112(m): 11:58am On Aug 04, 2019 |
please I want solve this problem and I need guidance please.. someone should help/Guide me... here is the problem.. 1. obtain the angle between the lines 2y-4x+6=0 and y-2x-5=0 2.determine the distance between the line 4x-6y=6 and 3-3y+2x=0 3. Find the locus of a variable point P, if the distance of P from the X-axis is always three times its distance from the point (3, -3) please mathematicians/physicians in the house should help abeg |

Miracle112:You mean Physicists ![]() ![]() ![]() ![]() Physicians are related to medicine and similar stuffs. |
Re: Nairaland Mathematics Clinic by Nobody: 5:58pm On Aug 04, 2019 |
Miracle112:Carry SS1 further math textbook |
Re: Nairaland Mathematics Clinic by naturalwaves: 6:17pm On Aug 04, 2019 |
MathsEconomics:What application do you use to type. |
Re: Nairaland Mathematics Clinic by Miracle112(m): 6:37pm On Aug 04, 2019 |
naturalwaves: Okay Thanks Man for the correction. Can you helpe solve the problem? |
Re: Nairaland Mathematics Clinic by naturalwaves: 6:55pm On Aug 04, 2019 |
Miracle112:I will check it when I get home. You are welcome. |
Re: Nairaland Mathematics Clinic by Martinez19(m): 2:34am On Aug 05, 2019 |
Miracle112: here is the problem.. 1. obtain the angle between the lines 2y-4x+6=0 and y-2x-5=0Both lines are parallel since their slopes are equal hence the angle between them is zero. 2.determine the distance between the line 4x-6y=6 and 3-3y+2x=04x - 6y = 6 is equivalent to y = ⅔x - 1 . Also 3 - 3y + 2x = 0 is equivalent to y = ⅔x + 1 . Note that the distance, D between two parallel lines y = mx + a and y = mx + b is In your question, a = -1 , b = 1 , and m=⅔ Substituting and solving, we have that D = 6/√13 3. Find the locus of a variable point P, if the distance of P from the X-axis is always three times its distance from the point (3, -3) |y| = 3√[(x - 3)² + (y + 3)²] y²= 9[(x - 3)² + (y + 3)²] y² = 9( x² + y² - 6x + 6y + 18) 9x² + 8y² - 54x + 54y + 162 = 0 Completing the square and solving, you have (8/9)(x - 3)² + (64/81)(y + (27/8 ) )² = 1 This is an ellipse. please mathematicians/physicians in the house should help abegI have done that. It's physicists not physicians. |

Martinez19:Kudos bro. I was just about helping him out when I saw that someone has. Thanks |
Re: Nairaland Mathematics Clinic by Nobody: 1:51pm On Aug 13, 2019 |
An interesting inequality.

Re: Nairaland Mathematics Clinic by Nobody: 2:19pm On Aug 13, 2019 |
MathsEconomics:After solving this problem I have arrived at the conclusion that there are no solutions. |
Re: Nairaland Mathematics Clinic by Nobody: 4:32pm On Aug 13, 2019 |
Darivie04: Can you continue from here?
|
Re: Nairaland Mathematics Clinic by Darivie03: 5:43pm On Aug 13, 2019 |
MathsEconomics:No like I actually solved the problem. My solutions included complex numbers meaning one where x,y,z are real numbers doesn't exist. I solved it by factorizing equation 2 and 3 to obtain the values of x+y+z(given in the question to be 0), xyz(=6) and xy+yz+xz(=7). Then used the cubic equation idea you mentioned. |

Darivie03: There are actually two choices for t. t=±7 Here's a recurrence relation to use to confirm this.
