Putting the right kind of strain on a patch of graphene can make super-strong pseudo-magnetic fields, a new study says. The finding sheds new light on the properties of electromagnetism, not to mention the odd properties of graphene. More »
I have a torrent with some red spots on the Availability graph. How can I find these last few pieces of data so that the torrent doesn't stay incomplete forever?
I need to be able to reference the equation of the trend line obtained on a graph in Microsoft Excel 2007.
I know I can just type the equation but my instructor would like the whole process to be automatic. Just change the values and everything should change with it. Including data which relies...
My TI-84 Plus Silver Edition calculator won't graph more than one equation on "Y="?
I don't know what happened but my graphing calculator won't let me graph more than one line at a time. If I enter another line on my next "Y=", it won't show up but it the previous graph will show. I tried...
I have been researching for my homework and came up with this data, unfortunately im not familiar with excel 2007. i need to create a line graph demonstrating two lines that are growing. here is what its like:
US output: 13.2 trillion dollars, and grows at 3.4% a year.
Chinese output: 2.8...
I have just normal graphs on my TI 84, with some shading, and I went to turn the axes off and all the sudden I couldn't access my graph cause it said ERR:UNDEFINED. And believe me, turning the axes on didn't do anything. This problem has been going on all day and I found a mistake in an equation...

...however, as everyone knows 1998 was an extraordinarily hot year, due almost entirely to one of the strongest El Niño events ever recorded.
So...throwing out the 1998 outlier, isn't the trend one of...
why does the graph of x^(2/3) only exist on domain of (0,infinity)?
if i plugged in a negative value say, -1 (negative one)...... via 3*sqrt((-1)^2) "the 3rd root of negative one squared"....i would get an output of -1........on the otherhand if i plugged in -1^(2/3) or "negative one raised to...
