Homework Statement
Our setup:
Connect the transformer to an LRC-series circuit(L= 2mH with iron core,C=1mF and R=10Ω). Use the 2V and 6V outputs of the transformer, the effective voltage supplied by the transformer will then be 2 V.
Use the digital multimeter to measure the effective...
For the people who are still interested, after watched the solution, the key was to first determine the series of g(x)=A/(x-B) using the geometric series (1) and then take the third derivative of both sides of the equation obtained by step 1
Then the c disappears in the nominator and my f(x) is again f(x)= A/(x- B)4 after put the c in??
And is my tactic for solving this problem, with taking the 4√ the good tactic, or is it totaly the wrong way to solve it?
The question is:
Determine the Taylor series of f(x) at x=c(≠B) using geometric series
f(x)=A/(x-B)4
My attempt to the solution is:
4√f(x) = 4√A/((x-c)-B = (4√A/B) * 1/(((x-c)/B)-1) = (4√A/-B) * 1/(1-((x-c)/B))
using geometric series : 4√f(x) = (4√A/-B) Σ((x-c)/B)n
f(x)= A/B4 *...
My homework question is about the first law of blackbody radiation. I have to prove an expansion when
for KT≫ℏw.
After some rewriting of the formula i have (ex-1)-1
because KT≫ℏw, x is close to zero, so i think i should use the maclaurin series.
According Wolfram Alpha the series expansion is...
The question is about 2 sticks standing above each other, but i have a more general question.
The position of my mass is described by: (2rsin(a) - rsin(b) , 2rcos(a)+rcos(b))
the goal is to get a formula for the kinetic energy, so i need the speed of the mass.
If i take the derivatives of...
