Post your answer to the equations here.

Answer 1

x=-700/33
y=-487/11

Answer 2

How can I "Unmedal" you:-)

Answer 3

Did you get the same? I guess you would as the work is accomplished by a math engine lol

Answer 4

**For Neophytes that don't know of Wolfram** :-)

Answer 5

Apparently all Neophytes know of Wolfram...

Answer 6

I didn't know about it until I found this open study, a real neat thing. I wonder how long it has been around!

Answer 7

Really, Oh! Maybe I should medal u after all, lol.

Answer 8

A few years ago he started it, 4 maybe..

Answer 9

I entered a cubic equation and it solved it!

Answer 10

The cute thing is that you can often use natural language..

Answer 11

eg Put limit 1/x

Answer 12

amazing! It is nice to have that tool available. Now only word problems will be stressful lol

Answer 13

O.K

Answer 14

amistre64's sanity check

Answer 15

I got plus minus infinity with a real nice graph.

Answer 16

amistre64 is now hung up on colors lol

Answer 17

Try

eigenvalues {{4,1},{2,-1}}

Answer 18

OK

Answer 19

or

integrate sin x dx from x=0 to pi

Answer 20

or

5, 14, 23, 32, 41, ...

Answer 21

I did the eigenvalues, got the answer and I don't even know what I did Haven't had eigen value, I did see the tables, so I guess it is a matrix thing?

Answer 22

Yes, leads to invariant lines under transformations.

Answer 23

yay everybody gets medals!

Answer 24

Only if you post an interesting Wolfram computation.

Answer 25

okay sure..

Answer 26

Thanks for showing the ability to input problems and how friendly that engine is!

Answer 27

You are welcome, I hope there are some others who will benefit.

Answer 28

wolfram cannot integrate my stuff...

Answer 29

http://www.wolframalpha.com/input/?_=1310045212140&i=Integral(Integral(Integral(sqrt(x%2by%2bz)e%5e(x%2by%2bz)%2cx%2c-infinity%2cinfinity)%2cy%2c-infinity%2cinfinity)%2cz%2c-infinity%2cinfinity)&fp=1&incTime=true

Oh well turns out it doesnt converge anyway..

Answer 30

And Wolfram says it doesn't right?

Answer 31

yup...

Answer 32

One more for luck

div (x^3 y, y^3 z, z^3 x)

Answer 33
