Sample Question 1
Which is compact in Rn?

{(x1,x2,x3,……….xn ) ∶ |xi | ≤ 1, 1 ≤ i ≤n}.

{(x1,x2,x3,……….xn ) ∶ x1+x2+x3+......+xn=0}.

{(x1,x2,x3,……….xn ) ∶ xi > 0, 1 ≤ i ≤ n}.

{(x1,x2,x3,……….xn ) ∶ 1≤ |xi | < 2, 1 ≤ i ≤ n}.

Sample Question 2
If G is an open set and f : G → C is differentiable function then

F is analytic on G

F is non-analytic on G

F is constant on C

None of these

Sample Question 3
Listed below are four subsets of C2. Which is bounded in C2. ( R(z) denotes real part of z )

{ (z,w) ∈ C2 : z 2+w 2 = 1}

{ (z,w) ∈ C 2 : | R(z)| 2+ |R(w)| 2=1}

{ (z,w) ∈ C 2 : |z| 2+ |w| 2 = 1}

{ (z,w) ∈ C 2 : |z| 2 - |w| 2 =1}
