It still creates arcs through the air even when there is no metal nearby. I was wondering if a fly within range would be a path of least resistance for the electricity built up in the coil
ok, so for the people reading this in the future, the actual useful info so far is;
Cylinder:
z=\pm\,\sqrt{\text{radius}^2-y^2}
Sphere:
z=\pm\,\sqrt{\text{radius}^2-x^2-y^2}
Bowl:
z=\frac{1}{radius}(x2+y2)
Cone:
z=\frac{1}{radius}\sqrt{x^2+y^2}
That pretty much covers it I think.
Depends on you and your instructor I guess. I just finished DiffEq this semester. Made A's in all of my math classes since the beginning of college. If you ask me anything from those classes I will have to look it up though. The only benefit the class gave me is that I know it exists and I can...
I just wanted a quick reference of all of the solids, solved for z in Cartesian coordinates, not a lesson on learning them again. There is no long-term benefit to re-learning these equations. I will forget them again anyway. I just need a reference. I'll eventually have them listed and then some...
For anyone's future reference, here's the answer for a cylinder:
Centered on the x axis:
z=\pm \sqrt{radius2-y2}
Centered on the y axis:
z=\pm \sqrt{radius2-x2}
Now we just need the other ones..
(x−h)2+(y−k)2=r2
That's the equation of a circle and it is of no use in answering my question.
Let me explain it another way. Let's way you had to make a cylinder show up on a 3d graphing calc that only uses Cartesian coordinates. Ignore everything else and simply accomplish the goal...
ok so center it on the y or x-axis instead. Then you will have two equations which combine to graph a horizontal cylinder. What would that equation be?
It must be possible to graph a cylinder in Cartesian coordinates..
I've taken calc 3. I'm familiar with the other coordinate systems and their benefits. I literally want what I was asking for which is the equations, in rectangular form (hence the "entered into a graphing calc" statement), for...
I've tried googling this but I can't find the answer. I'd like all of the common 3d shape equations if someone has them. THEY HAVE TO BE SOLVED FOR Z so they can actually be graphed on a 3d graphing calc. For some crazy, crazy reason, these equations are never listed solved for z or, don't even...
y"-8y'+20y=tet, y(0)=0, y'(0)=0
I need to know if I made a mistake in getting to the step below:
L-1{ 1/[(s-1)2(s2-8s+20)] }
because when I solve that, I get something pretty gnarly..
