- peerk, on 10/12/2007, -0/+1"(122.78+(x^2))/190)=.93"
That's pretty easy to solve on your own. I mean really easy. It would probably take just as long to type it in and hit search as it would to do with an old school vanilla calculator and a sheet of paper.
Maybe the submitter just gave an easy example so he wouldn't confuse all the 6th graders on digg :) - tsupersonic, on 10/12/2007, -0/+1My scientific calculator could handle solving for x, but I use my TI-89 instead for its advanced math purposes. Anyways, its a cool feature, and also Google can do simple math, like 2+2
- kimos, on 10/12/2007, -0/+1Not useful for school unless it left the answer in the form of integer expressions and fractions. If you answer a calculus problem with a decimal, you won't get any marks...
- kcblah, on 10/12/2007, -0/+1Theres a tool that does this (I think) and gives you the steps also, it cant do everything in the equation, but it will make an equation much simpler. http://www.algebrahelp.com/
Use the calculators, hell of a lot better than a normal calculator. - balazs, on 10/12/2007, -0/+1this seems pretty cool, but i will still use google, it is much better
- paulbram, on 10/12/2007, -0/+1Actually, MSN search has lots of cool things like this. Try asking it any question. Such as "What is the capital of Minnesota?"
- twistymcgee, on 10/12/2007, -0/+1It would be even more useful if it could show you how it got the answer. Then it becomes a learning tool.
- hijinks, on 10/12/2007, -0/+1i dont know about any of your math teachers in highschool but mine actually made us show the work.. and if you have the right answer you can easily check it anyway..
- fuelvolts, on 10/12/2007, -0/+1This was the main reason I bought a TI-89 instead of the "required" TI-83 in HS (and currently use in college).
F2-Solve-type equation-get right answer without thinking
It has come in handy many of times! - inactive, on 09/06/2008, -0/+1The best mortgage rates, refinance, home loan, real estate, realty http://tophomemortgageloan.com
- peace, on 10/12/2007, -0/+1It can't solve equations with complex solutions like ... x^2+2=0
- dado1945, on 10/12/2007, -0/+1Actually I doubt that this feature will not be removed soon. It can solve equation x^3+x^2+x=1 but can't solve x^3+x^2+x=-2. However it seems it is trying to solve it and is doing it really slow - or is it lag on my side?
- Hergio, on 10/12/2007, -0/+1Yeah, you still need to know how to do the stuff. But its a nice check.
Google has a relatively simpler calculator available, but it won't solve equations...at least not yet.
http://www.google.com/help/calculator.html - Battlecry, on 10/12/2007, -0/+1@dado1945:
MSN's not the only one who can't solve that problem... Algebrahelp couldn't either.
Simplifying
x^3 + x^2 + x = -2
Reorder the terms:
x + x^2 + x^3 = -2
Solving
x + x^2 + x^3 = -2
Solving for variable 'x'.
Reorder the terms:
2 + x + x^2 + x^3 = -2 + 2
Combine like terms: -2 + 2 = 0
2 + x + x^2 + x^3 = 0
The solution to this equation could not be determined. - Allanon, on 10/12/2007, -0/+1Two sites from previous Digg posts that will help with the math:

x=1
1^1=1
Wow, that was hard...

You failed to get complex number solutions, you get 20% mark, you failed your exam. - BlackMamba, on 10/12/2007, -0/+0Cool feature indeed, no denying. Wish this was available a year back though.
Anyway, Good going MSN! - VSack, on 10/12/2007, -0/+0paulbram said:

Actually to your actually, but Google can do the same exact thing. You can also type in "population of Minnesota" and get the same exact results from both browsers.
However, I can type in "A history of Violence" into Google. and it comes up with Title, running time, average rating (simliar to rotten-tomatoes or metacritic) and more. Microsoft has yet to *borrow* this idea from Google. - TWiTsoldier, on 10/12/2007, -0/+0"but you can't solve x^x = 1 either, lol."
x=1
1^1=1
Wow, that was hard...
Anyways, by the time it takes to actually properly enter the equation into the solver, you could have gotten the answer by hand. No digg. - hypercrypt, on 10/12/2007, -0/+0Google does complex numbers!!! MSN can't even do ln(-1). And its not like it can solve HARDER equasions such as x^x=1, lol.
no digg - antoniojvr, on 10/12/2007, -1/+1Ahh yes. Let's make Americans worse at math by having the Internet do their homework.
- fr3nch13, on 10/12/2007, -2/+2Because google users are smart enough to figure it out themselves.
- catullus, on 10/12/2007, -0/+0i think what snoopy meant was root(-1) is imaginary. and as for some commenter earlier who said the numbers i put in were simple, yeah, they were, i was just trying to demonstrate the concept
- danguy, on 10/12/2007, -0/+0Mathematica has no problem solving x^3+x^2+x=-2:
{{x -> -1.3532099641993274},
{x -> 0.1766049820996636 + 1.2028208192854806*I},
{x -> 0.1766049820996636 - 1.2028208192854806*I}}
Alternatively:
{{x -> (-1 - 2*(2/(-47 + 3*Sqrt[249]))^(1/3) +
((-47 + 3*Sqrt[249])/2)^(1/3))/3},
{x -> -1/3 + ((1 + I*Sqrt[3])*(2/(-47 + 3*Sqrt[249]))^
(1/3))/3 - ((1 - I*Sqrt[3])*
((-47 + 3*Sqrt[249])/2)^(1/3))/6},
{x -> -1/3 + ((1 - I*Sqrt[3])*(2/(-47 + 3*Sqrt[249]))^
(1/3))/3 - ((1 + I*Sqrt[3])*
((-47 + 3*Sqrt[249])/2)^(1/3))/6}} - inactive, on 10/12/2007, -0/+0but you can't solve x^x = 1 either, lol.
- smickles, on 10/12/2007, -0/+0How long until Google has this tho now?
- inactive, on 10/12/2007, -0/+0google is evil!!!, support Booble
- friegh, on 10/12/2007, -1/+1no digg...If you need to use a search tool to do your algebra homework, its no wonder IBM is giving bonus's to their employee's to teach math and science. Algebra, calculus, trig...its all the same a matter of patterns, once you figure out the pattern it becomes redundant. That's why I majored in math, the homework was easy, my engineer friends spent all their time doing the same problem over and over again with different numbers while I proved that it would work in all cases (given the constraints) and then going to the bar
- tempusrob, on 10/12/2007, -1/+1I hope Google launches a tool to solve differential equations in retaliation.
Hey, I can dream can't I? Besides, it'd more realistic a speculation than a GoogleOS... - snoopy, on 10/12/2007, -0/+0Yeah, but it doesn't do imaginary numbers. -1
- inactive, on 10/12/2007, -0/+0well, well, well, in the future Google will do calculus problems so nyehhhh!
- Otto, on 10/12/2007, -0/+0"It can solve equation x^3+x^2+x=1 but can't solve x^3+x^2+x=-2."
Notice that when you solved the first one, it only gave you one answer. This is because the other roots of that problem are imaginary. In the case of the second problem, all the roots are imaginary. So there's no real solution.
Basically it can't handle complex numbers. If you'll notice, it has no problem with x^3+x^2+x=-4, but again, it only gives you the real root and not the imaginary ones. - sparkmonkeyz, on 10/12/2007, -0/+0yes, now i can do my homework in ike, QUICK and have more time to do do some digging!! score for me +digg
- jasqwerty, on 10/12/2007, -0/+0tan(pi/2) = 1.633124x10^16
Close enough I guess. LOL
But seriously, whoever said this isn't useful because you won't get any points if you give your answers in decimal form... enjoying HS I guess?
I haven't given a non-decimal answers in quite a number of years now. :-)
One of my professors used to take points OFF if you left stuff in irrational forms, plus, if you're going to be an engineer, forget radians and irrational forms. DD: Decimals & Degrees. - teknopagan, on 10/12/2007, -0/+0Anybody notice that it's not MSN Search solving these? It's getting its answers from MSN Encarta - note the Encarta Answers link below the solution.
- Gimmic, on 10/12/2007, -1/+0I concur. I wish this was around in HS.
- inactive, on 10/12/2007, -1/+0This would have been so cool when I was doing Calculus!!
- EnzanBlues, on 10/12/2007, -1/+0No kidding! I'm a senior with no math classes this year. I so could have used this the past few years. I guess just to make things faster, I could figure those problems out no problem.
- jwestbrook, on 10/12/2007, -1/+0I agree with fuel, my TI-89 has saved my butt many a times, plus teachers and professors let you use the 89 on tests and the like, but letting you use a laptop or a computer, much less a search engine....good luck
- ntnwwnet, on 10/12/2007, -1/+0neat. wish i'd had this in the early years of high school.
- TheProfessional, on 10/12/2007, -1/+0Too bad this still won't make people use MSN Search.
- inactive, on 10/12/2007, -1/+0-1 is an imaginary number? you sir are a moron.
- echimu, on 10/12/2007, -1/+0heh cool, finally MSN offers something useful :P but ill still go with Google :D
- N0_SkillZ, on 10/12/2007, -1/+0Blah Blah Blah.. MSFT builds on others ideas, they've been doing it since they IPO'd. See the business world really does corrupt :P
Support Google - Incognito, on 10/12/2007, -1/+0That's great. I was ready to flame MSN until I saw that.
- Urza_the_Tyrant, on 10/12/2007, -1/+0I wish I knew about this last year....//-_\ .
(+(+ WRYYYY!!!!!!!!+)+) - Hamsterpotpies, on 10/12/2007, -1/+0no more math homework!
- Dgen_X, on 10/12/2007, -1/+0pretty cool...and I just took the last algebra class I'll ever (maybe) have to take in my life
- ebenthurston, on 10/12/2007, -2/+0very cool. dugg.
