Question 5
Find all solutions of this system.
4x + 2y + 3z = 0 3x y + 2z = 0 x + 2y − z = 0
Compare the value of the determinant of the coefficient matrix
to zero using the nature of the solution.
Question 1
Using MATLAB solve the following system of linear simultaneous
equations
3x + 2y - z = 10........... [1]
-x + 3y + 2z = 5........... [2]
x - y - z = -1 .................[3]
s + 2t - 3u + 4v = 12........... [1]
2s + 2t - 2u + 3v = 10......... [2]
t + u = -1............................ [3]
s - t + u - 2v = -4................ [4]
y''+ 3y'+2y=e^t
y(0)=1
y'(0)=-6
Solve using Laplace transforms.
Then, solve using undetermined coefficients.
Then, solve using variation of parameters.
