6. If approximate solution of the set of equations, 2x+2y-z = 6, x+y+2z = 8 and -x+3y+2z = 4, is given by x = 2.8 y = 1 and z = 1.8. Then, what is the exact solution?
a) x = 1, y = 3, z = 2
b) x = 2, y = 3, z = 1
c) x = 3, y = 1, z = 2
d) x = 1, y = 2, z = 2
View Answer

Answer: c
Explanation: Substituting the approximate values x’ = 2.8, y’ = 1 z’ = 1.8 in the given equations, we get

2(2.8) + 2(1) – 1.8 = 5.8 …………..(i)
2.8 + 1 + 2(1.8) = 7.4 ……………..(ii)
-2.8 +3(1) + 2(1.8) = 3.8 …………..(iii)

advertisement

Subtracting each equation (i), (ii), (iii) from the corresponding given equations we obtain

2xe + 2ye – ze = 0.2 …………….(iv)
Xe + ye +2ze = 0.6 ………………(v)
-xe + 3ye + 2ze = 0.2 ……………(vi)

Where xe = x – 2.8, ye = y – 1, ze = z = 1.8.
Solving the equations (iv), (v), (vi), we get xe = 0.2, ye = 0, ze = 0.2.
This gives the better solution x = 3, y = 1, z = 2, which incidentally is the exact solution.

d) x = 1.64791, y = 1.14085, z = 2.08451
View Answer

Answer: d
Explanation: By Gauss Elimination method we get
\(\begin{bmatrix}
1 & 4 & -1\\
1 & 1 & -6\\
3 & -1 & -1\\
\end{bmatrix} \) \( \begin{bmatrix}
x\\
y\\
z\\
\end{bmatrix}\) = \( \begin{bmatrix}
-5\\
-12\\
4\\
\end{bmatrix} \)

By R2-R1 and R3-3R1
\(\begin{bmatrix}
1 & 4 & -1\\
0 & -3 & -5\\
0 & -13 & 2\\
\end{bmatrix} \) \( \begin{bmatrix}
x\\
y\\
z\\
\end{bmatrix}\) = \( \begin{bmatrix}
-5\\
-7\\
19\\
\end{bmatrix} \)

R3-(-13/-3)*R2
\(\begin{bmatrix}
1.0000 & 4.0000 & -1.0000\\
0 & -3.0000 & -5.0000\\
0 & 0 & 23.6667\\
\end{bmatrix} \) \( \begin{bmatrix}
x\\
y\\
z\\
\end{bmatrix}\) = \( \begin{bmatrix}
-5\\
-7\\
49.33333\\
\end{bmatrix} \)

x+4y-z = -5
-3y-5z = -7
23.6667z = 49.3333
Hence, z = 2.08451
-3y = -7+5z
Hence, y = -1.14085
x = -4y+z-5
Hence, x = 1.64791.

11. Which of the following is the advantage of using the Gauss Jordan method?

12. Apply Gauss Elimination method to solve the following equations.

2x – y + 3z = 9
x + y + z = 6
x – y + z = 2

a) X = -13, y = 1, z = -8
b) X = 13, y = 1, z = -8
c) X = -13, y = 4, z = 15
d) X = 5, y = 14, z = 5
View Answer

Answer: c
Explanation: 2x – y + 3z = 9 ……….(i)
x + y + z = 6 ……………………(ii)
x – y + z = 2 ……………………(iii)

To eliminate x, operate (ii) – (iii)
y = 4
Now, operate (i) – 2(ii),
-3y + z = 3
Now by back substitution,
Z = 15
X + 4 +15 = 6
X = -13.

14. Find the inverse of the following matrix?
\(\begin{bmatrix}1&-1&1\\1&1&1\\1&2&4\end{bmatrix}\)
a) 1/6 \(\begin{bmatrix}1&1&1\\0&-1&1\\1&3&4\end{bmatrix}\)
b) 1/6 \(\begin{bmatrix}1&-1&1\\8&1&6\\1&2&4\end{bmatrix}\)
c) 1/6 \(\begin{bmatrix}1&1&1\\5&-1&6\\1&6&4\end{bmatrix}\)
d) 1/6 \(\begin{bmatrix}1&-1&1\\1&1&1\\1&2&4\end{bmatrix}\)
View Answer

Answer: d
Explanation: We have, the minor of the (1, 1) entry is \(\begin{vmatrix}1&1\\2&4\end{vmatrix}\)
The minor of the entry (1, 2) is\(\begin{vmatrix}1&1\\1&4\end{vmatrix}\)
Repeating this process, the matrix of minors is
\(\begin{pmatrix}2&3&1\\-6&3&3\\-2&0&2\end{pmatrix}\).
Next we negate every other entry, according to the pattern
\(\begin{pmatrix}+&-&+\\-&+&-\\+&-&+\end{pmatrix}\).
The matrix of minors becomes
\(\begin{pmatrix}2&-3&1\\6&3&-3\\-2&0&2\end{pmatrix}\).
Transposing, we get \(\begin{pmatrix}2&6&-2\\-3&3&0\\1&-3&2\end{pmatrix}\).
In order to divide by the determinant we must first compute it.
We can compute that det = 6.
Hence,
A-1 = \(\frac{1}{6}\begin{pmatrix}2&6&-2\\-3&3&0\\1&-3&2\end{pmatrix}\).

15. Which of the following transformations are allowed in the Gauss Jordan method?

x\\
y\\
z\\
\end{bmatrix}\) = \( \begin{bmatrix}
9\\
13\\
40\\
\end{bmatrix} \)
By R2-2R1 and R3-3R1

\(\begin{bmatrix}
1 & 0 & 0\\
0 & 1 & 0\\
0 & 0 & 1\\
\end{bmatrix} \) \( \begin{bmatrix}
x\\
y\\
z\\
\end{bmatrix}\) = \( \begin{bmatrix}
0.33\\
1\\
1.67\\

c) x = 1.5, y = 2.2, z = -0.5
d) x = 1.5, y = 2.2, z = -0.5
View Answer

Answer: b
Explanation:
∆ = \(\begin{pmatrix}1&1&1\\1&-1&1\\1&2&3\end{pmatrix}\) = -4

X = (1/∆) = \(\begin{pmatrix}6.6&1&1\\2.2&-1&1\\15.2&2&3\end{pmatrix}\) = -4.8/-4 = 1.2

Y = (1/∆) = \(\begin{pmatrix}1&6.6&1\\1&2.2&1\\1&15.2&3\end{pmatrix}\) = -8.8/-4 = 2.2

Z = (1/∆) = \(\begin{pmatrix}1&1&6.6\\1&-1&2.2\\1&2&15.2\end{pmatrix}\) = -12.8/-4 = 3.2

Hence, x = 1.2, y = 2.2, z = 3.2.

a) Iterations
b) False positions
c) Successive displacement
d) Eliminations
View Answer

Answer: c
Explanation: Gauss Seidal method is also termed as a method of successive displacement because with the iterations, we keep on displacing the values we select for the unknowns which are used in the subsequent steps.

22. Solve the following equation by Gauss Seidal Method up to 2 iterations and find the value of z.

27x + 6y - z = 85
6x + 15y + 2z = 72
x + y + 54z = 110

a) 0
b) 1.92
c) 1.88
d) 1.22
View Answer

Answer: b
Explanation: From the given set of equations-
x=\(\frac{(85-6y+z)}{27}\)
y=\(\frac{(72-6x-2z)}{15}\)
y=\(\frac{(110-x-y)}{54}\)

1st iteration:
y=0, z=0
x=\(\frac{85}{27}\)=3.14
x=3.14, z=0
y=\(\frac{72-(6×3.14)-2×(0)}{15}\)=3.54
x=3.14, y=3.54
z=\(\frac{110-3.14-3.54}{54}\)=1.91

2nd iteration:
z=1.91, y=3.54
x=\(\frac{85-(6×3.54)+(1.91)}{27}\)=2.43
z=1.91, x=2.43
y=\(\frac{72-(6×2.43)-2×(1.91)}{15}\)=3.57
y=3.57, x=2.43
z=\(\frac{110-2.43-3.57}{54}\)=1.92
Thus, after the second iteration
x=2.43, y=3.57, z=1.92.

23. What is the condition applied in the factorization method?
a) There must exist a diagonal matrix form of the given matrix
b) Matrix should not be singular

a) 1.571
b) 7.358
c) 7.853
d) 7.538
View Answer

Answer: a
Explanation: By Secant Method the iterative formula is given as:
x(n+1)=\(\frac{x(n-1)f[x(n)]-x(n)f[x(n-1)]}{[f[x(n)]-f[x(n-1)]]} \)
For n=1
x(2)=\(\frac{x(0)f[x(1)]-x(1)f[x(0)]}{[f[x(1)]-f[x(0)]]} \)
x(0)=1 and x(1)=2, f(x0)=-8 and f(x1)=6
Hence x2= 1.571.

a) 0.8878784
b) 1.9878785
c) 1.18878784
d) 1.8878784
View Answer

Answer: c
Explanation: Here,
x0 = 0
x = 0.18
h = 0.1
x = x0 + nh,
0.18 = 0 + n(0.1)
n = 1.8

x y Δy Δ2y Δ3y Δ4y
0 1 0.052 0.1174 -0.1583 0.2126
0.1 1.052 0.1694 -0.0409 0.0543
0.2 1.2214 0.1285 0.0134
0.3 1.3499 0.1419
0.4 1.4918

y0 is 1 since it is forward interpolation formula.
Δy0 = 0.052
Δ2y0 = 0.1174
Δ3y0 = -0.1583
Δ4y0 = 0.2126
Substituting in the formula,
f(x) = y0 + nΔy0 + n(n-1)Δ2y0/2! + n(n-1)(n-2) Δ3y0 /3! +….
\(f(0.18)=1+(1.8)(0.052)+\frac{(1.8)(0.8)(0.1174)}{2}+\frac{(1.8)(0.8)(-0.2)(-0.1583)}{6}\)
\(+\frac{(1.8)(0.8)(-0.2)(-1.2)(0.2126)}{24} \)
f(0.18) = 1.18878784.

28. Which of the following is an assumption of Jacobi’s method?
a) The coefficient matrix has zeroes on its main diagonal
b) The coefficient matrix has no zeros on its main diagonal
c) The rate of convergence is quite slow compared with other methods
d) Iteration involved in Jacobi’s method converges
View Answer

Answer: b
Explanation: This is because it is the method employed for solving a matrix such that for every row of the matrix, the magnitude of the diagonal entry in a row is larger than or equal to the sum of the magnitudes of all the other (non-diagonal) entries in that row. This helps in converging the result and hence it is an assumption.

5 -2.75 -2.6875 -2.71875 (+)
6 -2.71875 -2.6875 -2.703125 (-)

Hence we stop the iterations after 6. Therefore the approximated value of x is -2.703125.

30. Find the positive root of the equation x3 – 4x – 9 = 0 using Regula Falsi method and correct to 4 decimal places.
a) 2.7506
b) 2.6570
c) 2.7065
d) 2.7605
View Answer

Answer: c
Explanation: f(2) = -9
f(3) = 6
Therefore, root lies between 2 and 3
a = 2; f(a) = -9
b = 3; f(b) = 6
Substituting the values in the formula,
\(x = \frac{bf(a)-af(b)}{f(a)-f(b)}\),
we get \(x1 = \frac{3(-9)-2(6)}{-9-6}\)=2.6; f(x1) = -1.824
Therefore, x1 becomes a to find the next point.
\(X2 =\frac{3(-1.824)-2.6(6)}{-1.824-6}\)= 2.693251534; f(x2) = -0.23722651
Therefore, x2 becomes a to find the next point.
\(X3 = \frac{3(-0.23722651)-2.693251534(6)}{-0.23722651-6}\)=2.704918397; f(x3) = -0.028912179
Therefore, x3 becomes a to find the next point.
\(X4 = \frac{3(-0.028912179)-2.704918397(6)}{-0.028912179-6}\)=2.70633487; f(x4) = -3.495420729*10-3
Therefore, x4 becomes a to find the next point.
\(X5 = \frac{3(-3.495420729*10^{-3})-2.70633487(6)}{(-3.495420729*10^{-3})-6}\)=2.706505851; f(x5) = -3.973272762*10-4
Therefore x5 becomes a to find the next point.
\(X6 = \frac{3(-3.973272762*10^{-4})-2.706505851(6)}{(-3.973272762*20^{-4})-6}\)=2.706525285.
Therefore, the positive root corrected to 4 decimal places is 2.7065.
