So how would I go about coming to a vector equation?

:rolleyes::cry::cry::cry:

Can anyone help me, I have got probably an hour

I know z^2=x^2+y^2 is a cone.

Homework Statement Find a vector function that represents the curve of the intersection of two surfaces. Homework Equations z^2=x^2+y^2 with plane z=1+y The Attempt at a Solution So shouldn't it be r(t)=<cos(t), sin(t), 1+sin(t)> since x=cos(t), y=sin(t), and z= 1+sin(t)? The...

2) I don't think so, Kinetic E.=(1/2)mv^2, don't they different masses? What forcce acts on both of they equally?

Fix it to (6.6e^-4 moles Ba_{3}(PO_{4})_{2}) *\frac{2Na_{3}PO_{4}*12H_{2}0}{1 mole Ba_{3}(PO_{4})_{2}}*\frac{380.12 2Na_{3}PO_{4}*12H_{2}0}{2Na_{3}PO_{4}*12H_{2}0}

Whats similar about all three blocks? They all have the same acceleration. So F=ma ---> \frac{F}{block_{1}+block_{2}+bock_{3}}=a You can use that information to find the answers to your other questions.

I require at least 7 hours of sleep, but I don't mind the occasional 10 hours:biggrin:

Yah I have heard Mathematica can be super hard to learn, there is this huge manual I have seen before. I have heard between Mathematica and Maple that Maple is easier to learn so I will perhaps learn that one.

Yah I hear voices in my head: "Red Room! Red Room!":smile: Evo sounds right, if you really hear things see a doctor about it.

Yah I got this bad habit after an exam of having a couple cigerattes and drinks, and I don't smoke!:smile:

Its funny, before I take a test I get super stoked by listening to Slayer or other thrash metal. I go in and dominate. Works for me, in Calc got A's in all my exams, while the class average was like 67.4%. I am also trying to transition into being competitive. When I have a competitive...

Ok, so I have somehow obtained all three of these programs:biggrin: What I want to know is which is the easiest to learn?

Ah of course I get it now: r=\frac{1}{2}at^2 W=F*r \longrightarrow \frac{1}{2}ma^2t^2 \longrightarrow \frac{1}{2}m\frac{v^2}{t_{f}^2}t^2
