This stuff is easy, but this question is annoying me...

F(x, y, z) = (2xy^2 - yx, 2yx^2 + 2yz^2 - xz, 2zy^2 - xy)

I keep getting (0, y, x - z)
Anyone else get this? Anyone get (0, y, x - z)?

Wolframalpha's domain for the graph is wrong right? It should exist from (0, infinity) not R .

Hello /sci/, quick 2 questions. Need to simplify the following.

18. √7/8 (seven eighths)

19. 3√5 x √15

>He thinks expansion due to hydrogen bonding in ice is new information!

it seems unnecessarily difficult. and I mean the concepts are easy... the math to do them is fuckking hell.

the great beast of Physics..Kinematics.. in fact, there was a physicist who once said "there is a place in purgatory reserved for physicist who side with quantum theory, where they must teach kinematics every day for 10 hour lectures.."

>That's very nice, but how does one explain the incident where a woman claimed to have flown up on the roof during her "out of body experience", and seen a boot on the roof, and then when they went on the roof, they found the boot? Some things are just logically impossible to explain by conventional means.

Everyone on /Sci/ knows that depression and iq are not only impossible to realistically and accurately measure, and if they were they are just a fairy tale.

If the dr.said take the pills you should listen. Double up if you missed a dose.
