OH NO THEY ARE BURNING!!!!

can this question be answered?

?                                         

BUT, its says IF THEY COULD. so i say as much wood as they got.

its pretty self explanitory

5.40 / 18

8.40 / 30

Compare these two things above.....whichever is less.....that's the better buy....

21 duh lol

none b/c they have no hands

Work is equal to force times distance  (and Newtons times metres = Joules).  Can you do the calculation now?

.

There is a function called the gamma function that is related to factorials, but it is continuous.  When n is an integer then they are related by n! = gamma(n+1).

I guess the calculator here is trying to calculate gamma(3.4) as the continuous equivalent to 2.4!  However, it does it incorrectly, giving:

$${\mathtt{2.4}}{!} = {\mathtt{2.978\: \!344\: \!243\: \!007\: \!71}}$$

In fact gamma(3.4) = 2.9812064268...

(You can check this in WolframAlpha by typing gamma(3.4) in its input box)

90^2 = 8100

100^2 = 10000

And since  8464 lies between them....the square root has to be a number that lies between 90 and 100 and also ends with either a 2 or an 8. This last digit squared would end in a four......no other numbers between 90 and 100 would have an ending digit of 4 when squared.

Yes Chris, the problem is credited to Srinivasa Ramanujan (1187 - 1920). It appeared in the Journal of the Indian Mathematical Society in 1911. Apparently after about three months no one had come up with a solution, so he published the general result

$$x+1=\sqrt{1+x\sqrt{1+(x+1)\sqrt{1+(x+2)\sqrt{1+\dots}}}}$$

Try proving it as an exercise.

Substituting x = 2 gets you the stated problem with its answer.

your welcome

5.6*10^12/7*10^6     so we have

(5.6/7)  * (10^12/ 10 ^6)  =

.8 x 10^6  =

8 x 10^5

no it equals 25

How he made this !

$$\int {\frac{1}{\sqrt{4-(x-3)^2}} }\ dx
=\int
\frac{1}{\sqrt{4[ 1- \left( \frac{x-3}{2} \right)^2} ] }\ dx
=\frac{1}{2}\int
\frac{1}{\sqrt{1- \left( \frac{x-3}{2} \right)^2}}\ dx\\\\
\small{\text{We substitute:
$
\frac{x-3}{2}=\sin{(u)},
$
so we have
$
\frac{1}{2}\ dx=\cos{(u)}\ du
$
or
$
\ dx=2\cos{(u)}\ du
$
}}\\
=\frac{1}{2}\int
\frac{2\cos{(u)}}{\sqrt{1- \sin^2{(u)}}}\ du
=\frac{1}{2}\int
\frac{2\cos{(u)}}{\cos{(u)}}}\ du
=\int\ du=u\\
\small{\text{We substitute back:
$
u=\arcsin{ ( \frac{x-3}{2} ) }
$
}}\\\\
\int {\frac{1}{\sqrt{4-(x-3)^2}} }\ dx =\sin^{-1}{ ( \frac{x-3}{2} ) }$$

Thanks, Alan....I always forget that we can use Euler's "formula" on these...!!!

-5 + 6x - x^2 =

-5 - (x^2 - 6x )          complete the square on x...take one-half the coefficient on x

(= 3), square it (= 9)....then......add and subtract it...so we have...

-5 - (x^2 - 6x + 9 - 9) =

-5 + 9 - (x^2 - 6x + 9)       factor  the expression on the parenthesis

4 - (x - 3)^2

And that's it...

thank you Alan 

and sorry for the picture 

cosh(x) = (e^x + e^-x)/2

sinh(x) = (e^x - e^-x)/2  so

sinh(3*pi*i) = (e^3*pi*i - e^-3*pi*i)/2

Now e^iy = cos(y) + i*sin(y) so

sinh(3*pi*i) = (cos(3pi)+i*sin(3pi) - cos(3pi)+i*sin(3pi))/2 = i*sin(3pi) = i*0 = 0
