I'm currently in the process of building this project:

Here's the schematic:

I was wondering if it would be possible to power it with a 9.6...
Ok thanks all
I am glad I atleast did it right. I looked it up and e^x-e^-x/2 = sinh or something like that, but I guess that was my only mistake so I am happy.
Thanks for the replies
I did it with the chain rule and got
(2xe^2t)/(x^2 + y^2)^1/2 + -(2e^-2t)/(x^2 + y^2)^1/2
The answer is 2(s)^1/2(sinh4t)/(cosh4t)^(1/2)
I don't really understand this solution
Homework Statement
Find dw/dt. Check result by substitution and differentiation
w = (x^2 + y^2)^1/2, x = e^2t , y = e^-2tHomework Equations
The Attempt at a Solution
dx/dw = x/(x^2 + y^2)^1/2 dy/dw = y/(x^2 + y^2)^1/2
Dont really know where to go with it
Ok, It is for a multivariable calcul us class. Could I give a few examples and maybe you could explain them to me?
Find parametric rep. of Circle y^2 + 4y + z^2 = 5, x = 3
what curves are represented?
2 + r cos 4t, 6 + r sin 4t, 2t
