Any gurus of Maple or Mathematica here?

[yhelothar]

I'm trying to solve this messy equation:

solve((49*Pi)/4)-(1/2 x sqrt(49-x^2)+49/2 arcsin(1/7 x))-((49*Pi)/6)=0,x)

But it gives me a nonsensical answer:

7*cos(RootOf(3*_Z-Pi-3*cos(_Z)*sqrt(sin(_Z)^2)))

Why is it giving me the _Z's? There's only one variable to solve for, it should be able to do it.

No one? I thought ATOT would be filled with programmers and math people that should be familiar with these programs?

We can tell if you if the chick you re dating is fat.

I know in Mathematica, you need to have square brackets for a function of a name. Like sin[x] instead of sin(x)

Well first, you have a bracketing error. There's no opening to your solve function.

I'd love to help you, but I usually get some nonsensical answers in Maple as well. That program just pisses me off.

Hell I couldnt even figure out how to give a numerical answer instead of 900*pi for example. I'm sure there's a way... but eh whatever.

I may be way off, but in here:
1/2 x sqrt(49-x^2)

What are you trying to do? (1/2)*sqrt(49-x^2) or (1/2) * x * sqrt(49-x^2)?

ahh, nevermind, I can't help much.

I'm still working with maple 8 because my college hasn't forked over the money yet for maple 10, so it seems a bit different.

I don't think you need that for maple though.

Not sure what you mean. Do I have to put brakets in front of solve? I think maple may be different than mathematica.

For some reason... it works if I get rid of the last part: -(49*Pi/6), and it returns an answer of 7. So why does adding in a constant mess up the entire thing?

 

[thesurge]

Type allvalues(your answer)... it will give you the answers in a real format. I

hmmm I just got a numerical value for the last part, 49pi/6, and I used that instead, and I got 1.856451619.
Thanks for the help.

I'll simplify it & let you do the remaining part about solving for x, so that you feel that sense of accomplishment!

Your bracketing was messed, and for Mathematica you always have to capitalize the function names.

link doesn't work.. but I was able to solve for x anyways, as I explained in my previous post.
Thanks

This is going in my sig. Actually, I'm creating a sig to put this in. Fvcking nerds can't even do their job as a nerd. :laugh:
