Alright...so far I've been convinced there are great mathematicians in Nigeria....naturalwaves I salute you sir. As for the guyz saying Calculus cannot be applied in real life sense...Ever considered how the equations of motion came into existence?...Cars moves in accordance with our equations. Actually the questions i sent earlier on 're not thd hardest mathematics... I actually framed up this questions with the solutions known.....the password to myPc u guyz supplied were wrong..Did you consider PERMUTATION with repetition?


more questions loading...
Honestly , I have been so bored till I came across this thread. Thanks for making my day less boring. If you actually set those questions, then, I must commend you cos they seem to be application based and requires a bit of deep reasoning. Welldone and keep it up!

Mr. Naturalwaves.
Could you assist me with this question ?

A function of y={×, ×<_1}
. . . . . . . . . . . . . . {2-×, ×>2}.
Judge whether the function is continuous at ×=1. Differentiable at ×=1.
Thanks for the assistance.

u guys are pwedy good...naturalwaves guy u na boss o...i used to love maths back then but when i started doing some pwedy advanced maths i gave up to something less mathematics involved... guess i was lazy but then u know wat they say...do what u can do
Thanks bro. Some advance maths can be frustrating too.I think the key to that is getting the right textbooks.I observed overtime that some authors just rush through some concepts without a preciseand concise method. Thank God for the internet, one can get more than enough study materials online.

you don't have to be a guru to solve this. Its easy and please paraphrase your topic. Are you implying that many nairalanders are poor at maths?

I made sure I solved it correctly before reading the comments (I solved it just once and I got it right straight), so if I was able to solve it, then I don't think it's difficult! Was actually expecting some crazy maths #teamcomputerengineeringgraduate

Try harder. Check other numbers that end in 1 till it makes some sense!

A finite set "S" is defined by positive integers "x"...in which 5≤x≤50.
Two numbers exist in the set such that their sum is greater than the upper limit of the set by 5. The digits "057" is the mirrored image of the product of the two numbers (r&n). Calculate the solution of "nPr".



HINT: n>r,
S={5,6,...,r,...,27,...,n,...50}
nPr=n!/(n-r)!

kind of math that made man not grad from d dept of math, Unilorin....... very bad bad. thank jah for compt sci

That should be 121 then. Co-incidentally, that was the the answer I used to get an " S" first time. Check your mail.

I think the function is continuous but not differentiable at x= 1 cos after differenciating f(x) , there was no place to slot in 1 at all as it gave outright figures. Check what I got below and review with colleagues as it has been long I did this.

What is the Application of this maths?
I'm sure that nobody knows.
This is the biggest problem in our educational system.

(n, r) = (30, 25) since n+r = 55 (that is, their sum is greater than the upper limit of the set by 5)..

Thank you very much. Although we were told to plot a graph with the information, which is what I'm pondering. How will that be possible?

Re: HARDEST MATHS Question Ever by naturalwaves: 9:09am On Dec 22, 2014
Gerrard59:


Use the inequality values to obtain some figures. When you plot the graph, if there is no break at all when you are drawing the linem then the function is continuous but if there is a break in the line, the function is not continuous. You can check online for how to go about it, I am sure there would be more than enough materials. If I am free and settled, I may attempt plottiing the graph too (not promising o) but if I do, will let you see it.
