I guess I'm not asking this very well. I'm trying to solve the problem in parts but that's not helping me understand this any better. The full problem is...
z=(ex+y)/(ex+ey)
And I need to find the partial derivatives in respect to "x" and "y"
I am coming up with an answer that fully...
I'm sorry for being confusing. Yes I'm thrying to find the partial derivative of each item. I have no problems with partial derivatives that don't contain "e" but these I am having problems grasping.
Hey all. I'm having some problems with the partial derivatives of e. I understand the basics such as exy2. where I'm getting confused is with the following
dz/dx=e(x+y)
and
dz/dx=1/ex+ey
Can anyone help me out with understanding these??
Ok, that makes sense. So to write the series out in the long form for cosine you start at x=0 and work up from there? (such as to 1, 2, or 3) or do you work up in another manner such as in degrees or in terms of "x" such as x2, x3?
The question is Find the Macluarian Series for f(x)= cos x. Not a hard problem. What I'm having an issue with is Maclaurian series over all. I don't really understand them and how to use them. Our textbook discussion on it is not very helpful either. Can anyone point me in the right direction...
1. A 100N light is suspended from a beam with two wires. Both wires make angles of 40 degrees with the beam.
2. What is the tension in the wires?
3. Ok here's what I have so far...
Sum Fx: T2(cos 40)-T1(cos 40)=0
so T2=T1
Sum Fy: T2 (sin 40)+T1(sin 40+(-100)=0
so T2(sin 40)+T1(sin...
