Just type in any MATHS problem you have as far as undergraduate level and get correct solution in little time (please provide good details).

Waiting,

Any maths question at all,

Maths, is supposed to be an interesting subject. it should not be a reason to fail. I love maths, I do not know it all, but I can assist!

Let's go,

Let's have the first question for this thread,

Feel free to type in any maths question you have and lets solve them!

Be the first of your friends. . . . .

Good job Otooro.
Hopefully, the students will utilise this opportunity

Let's c who solves this. 1) F= e logxlogy (exponential logxlogy). Find fxy and fyx.
2) Toyin said d equations below are functionally dependent. Is she correct? Proof with workings. w1= xbyc (i.e x with power b and y with power c)
w2= blogx+clogy.

tnx. . . . other maths guru can also come up with questions and/or solutions.

2) Toyin said d equations below are functionally dependent. Is she correct? Proof with workings. w1= xbyc (i.e x with power b and y with power c)
w2= blogx+clogy.

tnx for the intervention, but the questions are not very clear, u can probably make the expression clearer. tnx a bunch!

Observe first that: (Regarding the first problem).

f0,infinity)x(0,infinity)----->(0,infinity)
               (x,y)---->e^(lnx.lny)

Now, f is a continuous map and so f_xy=f_yx.

Hence, f_xy = (f/xy)[1+lnx.lny].

Problem 2: Is not that clear, please get the question well posed. I hope this helps.

Nice one! This is the 'Ask Dr. Math' segment of Nairaland in the making.

I hope I can add some value.

Hint: the both questions r based on partial differentiation. I.e if u don't know partial differentiation, u can't know it. D 1st is on young's theorem under differentiation while d 2nd is on Jacobian's theorem under differentiation. Let's c who gets it.

Hmmm, Jacobian!

U mean no 1 can solve this? Great ife, i hail thee, these r part 1 questions in OAU. If i wait 4 a week and no 1 solves it, i will.

i hope u didn't get the question from prof. layeni, correct? lol. anyway, u can come up with the solution. tnx!

Guys please help me solve this maths question.

Need it urgently,
Thanks.

XYZ Ltd has a manufacturing process that processes light bulbs whose lifetimes are normally distributed with an arithmetic mean of 1,000 hours and a standard deviation of 200 hours.Determine the proportion of the light bulbs produced by the company with lifetime between 1,000 and 1,400 hours.

I really don't get this, question says ''on an island, there are only two kinds of people: those who are alwayshonest and those who alwayslie. Three of the inhabitants are talking; Andrea says: 'Barbara is honest', Barbara says 'Andrea and Ciro are both honest' and Ciro says 'Andrea is a liar'. We know that:
A. All three are honest
B. Andrea and Barbara are honest
C. Andrea is honest, Ciro and Barbara are liars
D. Andrea and Barbara are liars, Ciro is honest
E. All three are liars''

let me try...
B.Andrea and barbara are honest..

well my take is;
E) they are all liars

Prove that Cosec2(x) -cot(x)cosec(x)=1

Guys i think i hav a better clue...
Lets look at option D....andrea and babara are liars and ciro is honest..
If ciro is honest, it means that andrea is a liar from his statement and if andrea is a liar then from andrea's statemnt we can say that barbara is a liar and that gives us d whole content of d option D.
And that will aswell lead us to the statement of barbara being false.to justify that, for barbara 2 be a liar, 3 situations r involved,it cud be that both andrea and ciro r liar,andrea is a liar and ciro is honest and lastly andrea is honest while ciro is a liar..the situation that that justifies option D is the last..so option D is d best 4 me.
