y,my AC program gives the same results.
Strange,your process is also correct for theta=0.
I didn't take care of it and got 1 WA for this case.

My program gives the same result, too. But it still WA.
How about this test :
My program gives 57.299. I'm not sure if it's right or wrong

Strange ! I got exactly the same results. And I didn't use any epsilon in my program. I still get WA.
Can I post the code here?

I already wrote a generator for this problem so you can post your code here, I will use it to compare the answers

This is my program, thanks in advance

I use eps=1E-7 and pass it,
so I think eps is not main reason why you get WA.

by pdah
What is epsilon used for in this problem? I didn't use epsilon in my program.

oh,I see you used "float" in your code,change it to "double" and tried it again.the float type has no enough precision.
Posted: Sun Oct 28, 2007 7:09 am
by hi!man!
If I don't use epsilon, I will get WA because of precision error.
