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.
.

Chill bro, underway.

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.

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!

chrisviral:
Mailed!

Seen!

musachara:
done! cheers. you have to remove my quote from ur replly

Done.

chrisviral:
Teach me instead

No wahala.Mail me and let's fix a time.

musachara:
happy sunday bro. email me pls at.....

I have copied the mail and I have sent you a mail as well. Remove your email addy lest spammers get hold of it.

Nastydroid:
how are we goin to meet?

Send a PM.

musachara:
i actually began feeling disappointed at myself as an engineer, not until i saw how u solved it. lesson learnt #ifIntimidatedByAQuestion read it slowly without fear. Nice 1 bro

Exactly sir. Confidence is very important when trying to solve a question and then opening one's mind to digest the data and info inherent in the question followed by analysis of how it is going to be solved and the best approach. Happy sunday!

Nastydroid:
i left the competition early,the questions were beyond me I just dy watch for sideline

"He who fights and runs away, lives to fight another day". It will be better next time.

Nastydroid:
yes bro,so you still remember I want to brush up my skills for next year

Ofcourse, I do and some other guys like dejt4u, lebesque etc and stennon and co. It was fun! Lebesque solves like a machine in a jiffy.

Nastydroid:
can we also hook up

Why not? We can. You were on that maths competition thread right?

laryom1:
See your log cancelling....datz mathematically wrong....

Yeah, I have asserted that long ago, the funny thing is the way it seems to work for other similar problems liie the example above.

rapins:
Yes.

Good we are on the same page. Did you try the word problem on page 4 about the age of a woman and her husband? That's a bit trickish though I have solved it, you may want to try it too.

rapins:
Check your answer again. Y is number of women ie 60 not the other way round.

Thanks. I have resolved and I got "0.65054625" as the answer. Does this tally with yours?

jdbrasco:
u r gud bro. Jst use dat expression nd u will get ur radius.

Okay, thanks. n= (44/7)r^2. p=99/100. What does the E stand for? And what will be the value so we can solve for r? Thanks.

XXX5:
A Construction Firm wishes to use a group of fifty professionals to execute a project. These fifty are to be selected from 110 engineers. there are Y number of women in the firm and X number of men. The number of male engineers necessary to complete the project are 10100 to base two. If the firm consists of [(50!/49!)+(5²-√{225!/224!})] women, Calculate the value of... [(X²+Y³)25]/e10]+(65/{5×√4}²).


HINT: I refer to this question as a chain of EVALUATIONS in which only those able to manipulate Complexities are able to solve.
GOOD LUCK!

0.65054625

patwilly:
I just followed you. follow back bro.

Done.

jdbrasco:
bro, y equate prob to total n I.e 99/100=11r^2÷7? I think the expression E=nP comes in frm there; where n=44r^2÷7

You can take it up from there sir.I couldn't think of any other way to get the radius

XXX5:
If you add the age of a man to the age of his wife,
the result is 91. He is now twice as old as she was
when he was as old as she is now.
How old is the man and his wife?

The man is 52 years old and the woman is 39 years old. Find the solution attached below...

bataderemi:
I don't actually. nice try tho

Thanks.

mathefaro:
Yeah, he's very correct bro because if
(a + b) log x = log b, then
log x ^{(a + b)} = log b and
x ^{(a + b)} = b. (log 10 cancels each other)
Having said this, I thin the only logical solution to this is the graphical method. One has to draw a graph of y = 2 ^x and y = 4x on the same axis.

Thanks bro. I observed that the same method works for similar problems that was why I asked him to try it with 3^X = 9X

2sExy1:
Benin. It would have been nice to have you reboot my brain. Loved mathematics like mad before... changes happened to me.

Holla at me whenever you come around then and let's hook up.

bataderemi:
aiit... what are u studying?

Computer science at Msc level ( just got in)

bataderemi:
I think if there are 2 GH in 1 cm^2, then in A cm^2 there shld be 2A not A/2 grasshoppers. like
2=1
x=A
so x(1)=2A

Yeah, that will be 44/7 . Thanks. Let me edit.

bataderemi:
This is one of d ojoros that I mentioned sir, the part where u cancelled out d log, it ought to be 2^(x-2) not 2(x-2) tks.

You may be correct sir. Let me know if you have a better solution.

2sExy1:
You seem to have a flair for mathematics. That's nice. Where are you based?

Lagos. You?

bataderemi:
this is harder than d hardest....lol
the probability of finding at least a grasshopper in a circular field is 0.99, if the expected value of grasshoppers in 2 per cm squared, determine the radius of d field. not sure if d expectation is correct... U can just state how u will do it

This is just a try, you can review the solution and answer while we wait dor maths gurus to come try it too.....

bataderemi:
this question is a dead end, we cld not get it in secondary school unless we did ojoro

You can follow this simple method. Same can be used to solve 3^ X = 9X in which X= 3.

Ishilove:
I very much mind

. You are witty; you can make money from mild humour.

Ishilove:
You wanna teach me basic maths?

....Never too late if you do not mind.

Ishilove:
Stop...you're making me dizzy...

Stop...you're cracking my ribs.
