thankyouJesus: Wrong approach. |
Re: Nairaland Mathematics Clinic by Icosahedron(m): 12:20pm On Jun 01, 2017 |
thankyouJesus: That is a terrible way to approach the problem. I believe they are more sophisticated identities that could bail you out. |

Icosahedron:I dof my hat for you. Wrong approach! Smiles. Well, what do I know? |
Re: Nairaland Mathematics Clinic by thankyouJesus(m): 6:40pm On Jun 01, 2017 |
holuwajobar:Trying to solve this analytically may raise some eye lids. Use Falsi method to pick initial point, complete your solution with Newton Raphson method (Numerical Analysis). |

thankyouJesus: Given that sinA + sinB = x and cosA + cosB = y To solve this systems of equations. Sqaure both systems to obtain sin²A + 2sinAsinB sin²B = x² (*) cos²A + 2cosAcosB + cos²B = y² (**) adding we obtain 2 + 2(sinAsinB + cosAcosB) = x² + y² or 2 +2(cos(A-B)) = x² + y² *** cos(A-B) = (x² + y² - 2)/2 Complete the solution thankyoujesus and you shall obtain similar argument for tan(A-B) and use the half-angle identity to obtain the value of tan(A-B)/2 and then proceed to solve the original problem. |

Let a,b,c,d be numbers on the interval (0, 180) such that sina 7sinb =4(sinc + 2sind) cosa + 7cosb =4(cosc + 2cosd) Prove that 2cos(a-d) = 7cos(b-c), thankyoujesus you can actually use the method exemplified above to solve this problem. 1 Like |

Let ABC be a triangle, prove that (a+b+c)[tanA/2 + tanB/2] = 2cotC/2 |

Icosahedron:Your approach was highly sophisticated no doubt, welldone sir. Na you o, wetin I know. |
Re: Nairaland Mathematics Clinic by thankyouJesus(m): 12:58am On Jun 02, 2017 |
Icosahedron:Why post questions you have solution to? Post questions you don't have solution to so that people can help. I have lot to type based on our short memo but I dont take things personal. Word on marble, you are good no doubt but my working will also lead to same answer just that my approach is not sophisticated as you have rightly termed it, smiles. Be flexible, most Mathematics questions can be solved in variety of ways. Note: You can always beckon on me if you have Mathematics questions you can't solve. One love. |

thankyouJesus: Alright, I'll be sharing with you my Calculus assignments then if you UNIBEN accepts me since I don't like Calculus. As for the problems above, I didn't have answers to them when I shared the problem on this forum, it was an exercise in a textbook I was reading for Trigonometry. |
Re: Nairaland Mathematics Clinic by thankyouJesus(m): 12:08pm On Jun 02, 2017 |
Icosahedron:Okay then. |
Re: Nairaland Mathematics Clinic by Patbaker(f): 8:50am On Jun 03, 2017 |

Icosahedron:ARE you not the one that said, you want to share your calculus assignment ? |
Re: Nairaland Mathematics Clinic by Icosahedron(m): 4:21pm On Jun 03, 2017 |
Tollicin: Uhm.. Patbaker are you having problems on Calculus ![]() |
Re: Nairaland Mathematics Clinic by Patbaker(f): 9:55pm On Jun 03, 2017 |
Icosahedron: Lol I meant Please share ur calculus assignment with us as soon as possible ooo |
Re: Nairaland Mathematics Clinic by Icosahedron(m): 11:22pm On Jun 03, 2017 |
Patbaker: I understand we applied for the same course at UNIBEN, right? |
Re: Nairaland Mathematics Clinic by Patbaker(f): 9:39am On Jun 04, 2017 |
Icosahedron: Yeah i just hope we re all given the admission since the course is not competitive 1 Like |

Please, I want Mathematics scholars to solve this question for meTake this
Find x & y
If x^x^x=log3 and
x^y^y=log8. |
Re: Nairaland Mathematics Clinic by seunlly(m): 1:32pm On Jun 08, 2017 |
celenas:the variation question. answer is $2500. Factorization is 3 or 0.5. that third X does not have any coefficient |

rjek:Ordinary differential equation? It is exact. |
Re: Nairaland Mathematics Clinic by thankyouJesus(m): 3:35pm On Jun 08, 2017 |
celenas:1. You have to dismantle the shape into different shapes like triangle. Your knowledge of corresponding, alternate and opposite angle will be tested. 2. Use completing the square method. 3. Someone has provided answer already. |
