Solving the system of linear equations using the methods of Gauss-Jacobi and Gauss-Siedel. Using precision of 1x10^{-3}.
A=[-4 -1 2; 1 -10 6; 1 -3 -6]
B=[x1; x2; x3]
C=[1 -5 7]
A.B = C
Using Gauss-Jacobi I find:
I used x^0 = [0;0;0]. I can ?
With 11 iterations I find
X_1 =...
We determined the constants R and L of a coil by placing it in series with a standard resistor of 10 ohms and reading the voltages on the terminals of Rs, the coil and the series circuit complete. What are the values of R and L for the following voltage readings at 60 Hz:
Vrs = 20; Vcoil =...
Impedance -- Current phasor
In a series circuit of two elements, the voltage and current, for w = 2000 rad/s, are V = 150|-45° and I = 4,74|-116,6°.That variation in the frequency of the source would result in a phasor current of 6 amps? Assuming an unlimited variation in the frequency, what is...
A charge Q at a vertex of a square and another Q on the opposite corner of the square and other two charges q each of the other vertices. If the force eletrogmanetica on Q is null which the value of Q in terms of q? There is a q such that the resultant force on 4 charges is zero?

Find a general formula for the temperature u(x,t) in the form of a series with general formula for the coefficients of the series.
\alpha^2 \frac{\partial^2 u}{\partial x^2} = \frac{\partial u}{\partial t} with 0 < x < L; t>0
u(0,t) = 0
\frac{\partial u}{\partial x} (L,t) = 0 with t>0...
I find the equation of beat:
x(t) = [\frac{2F_o}{m(w_o^2 - w^2)}sin(\frac{(w_o - w)t}{2})]sin(\frac{(w_o + w)t}{2})
What values do I get to F_o, w_o and w to generate the graph ?
I use program maple to plot graph.
