Quick Test

(1 of 40) If

f (a) = \log |\frac{1 - a}{1 + a}|

for

a \neq \{- 1, 1\}

, then the set of values of all 'a', for which

f (\frac{2 a}{1 + a^{2}}) > 0

$(0, \infty) - \{1\}$
$(- \infty, 0) - \{- 1\}$
$(- \infty, \infty) - \{- 1, 1\}$
$(- 1, 1)$

(2 of 40) If the cofactors of the elements 3, 7 and 6 of the matrix

[\begin{matrix} 1 & 2 & 3 \\ 4 & - 1 & 7 \\ 2 & 4 & 6 \end{matrix}]

are a, b and c respectively, then

[\begin{matrix} a & b & c \end{matrix}] [\begin{matrix} 1 \\ 4 \\ 2 \end{matrix}] + [\begin{matrix} a & b & c \end{matrix}] [\begin{matrix} 3 \\ 7 \\ 6 \end{matrix}] =

-1

(3 of 40) Let

B = (\begin{matrix} 2 & 6 & 4 \\ 1 & 0 & 1 \\ - 1 & 1 & - 1 \end{matrix})

and

C = (\begin{matrix} - 1 & 0 & 1 \\ 1 & 1 & 3 \\ 2 & 0 & 2 \end{matrix})

. If a matrix A is such that BAC=I, then

A^{- 1} =

$(\begin{matrix} - 3 & - 5 & 5 \\ 0 & 9 & 14 \\ 2 & 2 & 6 \end{matrix})$
$(\begin{matrix} - 3 & - 5 & 5 \\ 0 & 0 & 9 \\ 2 & 14 & 16 \end{matrix})$
$(\begin{matrix} - 3 & - 5 & - 6 \\ 0 & 9 & 2 \\ 2 & 14 & 6 \end{matrix})$
$(\begin{matrix} - 3 & - 5 & - 5 \\ 0 & 9 & 2 \\ 2 & 14 & 6 \end{matrix})$

(4 of 40) If

\det (AB) = (\det A) (\det B)

and A is a non-singular matrix of order

3 \times 3

, then

\det (adj A) =

$\det (A)$
${(\det (A))}^{- 1}$
${(\det (A))}^{2}$
${(\det (A))}^{3}$

(5 of 40)

S = \{z \in C / |z - 1 + i| = 1\}

represents

a circle with centre (-1, 1) and radius 1 unit
a circle with centre (1, 2) and radius 5 units
a circle with centre (1, -1) and radius 1 unit
an ellipse with centre (1, -1)

(6 of 40) If

|z - \frac{2}{z}| = 2

, then the greatest value of

|z|

$\sqrt{3} - 1$
$\sqrt{3}$
$\sqrt{3} + 1$
$\sqrt{3} + 2$

(7 of 40) One of the

15^{th}

roots of -1 is

$cis 0$
$cis \frac{14 π}{15}$
$cis \frac{13 π}{15}$
$cis \frac{8 π}{15}$

(8 of 40) The product of the four values of

{(1 + i \sqrt{3})}^{\frac{3}{4}}

-8i
i
-8
8

(9 of 40) If one root of the equation

{ax}^{3} + bx + c = 0

is twice another root, then

$36 b^{3} = 343 {ac}^{2}$
$36 b^{3} + 343 {ac}^{2} = 0$
$36 b^{3} + 729 {ac}^{2} = 0$
$36 b^{3} = 729 {ac}^{2}$

(10 of 40) If

α

and

β

are the roots of the equation

2 x^{2} - 4 x + 3 = 0

, then

\frac{2 (α^{4} + β^{4}) + 3 (α^{2} + β^{2})}{α + β} =

-1
