1. ### What number of passengers will maximize revenue?

how was the equation gotten pls expalin
2. ### Area of an oval shape

i want to know if there is a formula for the area of an oval shape because i have been working on it and want to know if it has been discovered
3. ### Why is it difficult to integrate x^x

i tried doin it ,but always get to a place i cant continue.who can help integrate [(x^x)(1+LOG[X])]^2.All help will be appreciated
4. ### Strange integral

Hi, i was working with my teacher, and i discovered the continous differential of x!gives x!,also the continous integral to infinity of x! gives x!.how true is this ,also i wanted to know if the last number ever is going to be odd or even ,because from my point of view the ranges of all numbers...
5. ### Tricky Looking!

when differentiating functions of a variable say x raised to another function of xthen lets assume they are T^u,where t and u are fucntions of x,dy/dx = T^u[du/dx*logt+u(dt/dx)/t].now let 4-x=t,and u=5x. take normal procedures and see if it works

7. ### Remainder theorem

but my teacher gave us the problem,and said we should leave the answer in whole number not exponent.i guess abia must have posted series of these questions in other forms.so i still need help with it.i know the remainder is in the form (700^1/700)^(700^1/700).... but it should be a number
8. ### Another problem

area of rectangle with lenght x^x^x^x^x..... and breath y^y^y^y^y^y..... where x is 400^ 1/400 and y is 800^ 1/800. leaving answer in whole number not decimal or exponent
9. ### Differentiation question

how about the other question ,no one is talking about that ,just the easy one. the most important is x^(x^2)^(x^3)....
10. ### Another problem

how do i find the area of a rectanglewith sides 400root of 400 raised continously to itself like x^x^x^..and 800root of 800 raised also to itself continouslylike y^y^y... leave answer in whole number not exponent
11. ### Differentiation question

you are really funny juvenal. but then how about the other function, how can i get that differentiated?
12. ### N factorial

i guess it should be 2008.i mean n should be 2008.just a guess you might give it a try
13. ### Differentiation question

how can this be differentiated,i need to know how.x^x^x^x^x^x.... also ,my teacher posed this question to the whole class x^(x^2)^(x^3)^(x^4)................
14. ### Need another confirmation

that was a hard thing to say inha, how useless is it ,i just came across it and felt like letting the forum know how correct it is and u call it useless. thae was a hard thing 2 say
15. ### Need another confirmation

while working on the quadratic formula in school ,i came across another formula,and wanted to know if its been derived since i got this from the quadratic formula.the formula is as follows [-b^3-2abc +or- sqrt(b^6-12a^2b^2c^2-16a^3c^3)]/(2ab^2+4a^2c). please i want to know if it works for all.
