I need it for my physics class, we are running the plotting tool Grace.
I had it running on my computer (with some help)
So I think I may have downloaded everything I need to run grace,
but when I open up the cygwin terminal and type in xmgrace
it says
/usr/bin/xmgrace.exe: error...
ok well the wave equation is
y(x,t)=Asin(k(x-vt)+δ)
we know A, v,and k and we can sub them into get
y(x,t)=0.02sin(2.8(x-22.4t)+δ)
and expand
y(x,t)=0.02sin(2.8x-62.8t+δ)
to get δ we take the conditions given @t=0, y=.01m
x=0m( its at the driving end, I left this out in my initial...
in the form
y(x,t)=Asin(k(x-vt)+δ)
where p is the phase angle
A is .02m
v=22.4m/s
t=0.1s
k=2.80
wavelengh= 2.24m
at time t=0, the dispaclement(y) is 0.01m with dy/dt is negative
Im not sure how to findδ
1. Homework Statement
A U-tube has vertical arms of radii 'r' and '2r', connected by a horizontal tube of length 'l' whose radius increases linearly from r to 2r. The U-tube contains liquid up to a height 'h' in each arm. The liquid is set oscillating, and at a given instant the liquid in the...
Im sorry that I am having a hard time understanding
so df(x)/dx * Δx the dertivie of x^2 is 2x
so its 2x*1.000001
f(1.000001)≈2 Δx +1? if Δx =0.000001. so 2*0.000001 +1?
f(x) = (1 + x)^2
f'(x)= 2(1+x)
for very small values of x this would be 2, no?
Ok so v= πr2 h
the h would be the length, I think.
the r2 has to do with the raduis, but that's changing, doesn't chaning things like that have something to do with the ∫?
I do see that f(x) = x^2 it would be 1
and in f'(x) it would be 2
f(x+Δx)−f(x)≈df(x)/dx Δx
f(x+Δx)−1≈2 Δx
f(x+Δx)≈2 Δx +1
Like I don't understand how to use the formula maybe? I understand what a derive is and how to plug and chug numbers, just not this forumla or even how it applies...
