Let S be a surface such that x^2 + y^2 + 4z^2 = 1 (S is in R^3)
Let U be the fi nite region of S satisfying z > 0 and let C be the boundary of U.
Then: find a parametrisation of C.
I know the answe
5^2011 mod 7 ??? what the answer ??-By Fermats little theorem (or just by checking powers of 5)
5^6 = 1 (mod 7)
Therefore
5^2011 = 5^(6*335 + 1)= (5^6)^335 * 5^1= 1^335 * 5= 5 (mod 7).-Fermats little
There is an argument as to whether it is 9 or 1. Personally i think that it is 1, because by following BIDMAS (Brackets Indices Division Multiplication Addition Subtraction) you have to completely res
an = n^3 e^-2n
an = 2^2n/3^n-e^-2n=1/e^2n and e^2n=1+2n+(2n)^2/2!+(2n)^3/3!+(2n)^4/4!+…
so e^2n>2n^4/3 and n^3 e^-2n 0
as n-> inf.
2^2n=4^n so a(n)=4^n/3^n=(4/3)^2 and since (4/3)>1 a(n)-> infinity
I know the answer. Just trying to see how people will do :)-I think that in this division 6 is the dividend and the whole expression 2(2 + 1) is the divisor. Thus
6 ÷ 2(1 + 2) = 6 ÷ 6 = 1. The answer
My aunt, a botanist, records the height of a plant every day for a month. She wants to create a graph to show how the plants height changed over the month. What type of display should she use? A Line
Solve for x in the equation within the domain of 0
1+sinx.....cosx
----------+---------= 4cosx......1+sinx
Im totally stuck I have no idea what to do. Any help will be appreciated. Thank you very mu
Solve the following equation for all values of x: abs.(x+3)-9=2x
Please show work, im reallly confused due to the 2x being on the other side so im not quite sure how to solve this absolute value
Sort of like Hey, maybe I should invent a system of hieroglyphics and arrange them in different ways just so I can tell people they are doing it wrong?-math is natures way of deciding who should bag m
Explain why please! My AP test is Wednesday.
The function f is given by f(x) = sin ( (x + 1) / (x^2) ). Which of the following statements are true?
I. The graph of f has a horizontal asymptote at y =
Here is the problem that is on my final review that Im currently having trouble with:
Find the maximum and minimum values, if they exist over the indicated interval:
a) f(x)= 3x-8; [-2,1]
b) f(x)= x
Give a polynomial, of smallest degree, with integer coefficients whose roots are:
1, -(2^.5),3+i
this is a weird prob. bec. it has complex roots and square roots.
please show work and explain your p
