${f_n(z)}$ be a sequence of analytic function in a domain D such that $f_n$→f uniformly inD. Then $f_n’→f'$ uniformly in D. true/false
show that Lagz can have real value if and only if < is positive?
if x is the set of complex numbers whose real and imaginary parts and rational,what is Int x,x,8x?
wen people were asked if they felt that the laws covering the sale of firearms should be more strict, less strict or kept as they are now, 42% responded more strict., 15 responded less, 35% said keep them as they are now, and 8% had no opinion. If 10 randomly selected people are asked the same question, what is the probability that 5 will respond more strict, 2 less, 2 keep as the are and 1 have no opinion? Round your answer to three decimal places.
Suppose p is a polynomial with n distinct real roots. Show that p' has
at least (n-1) distinct real roots.

{fn(z)} be a sequence of analytic function in a domain D such that fn→f uniformly inD. Then fn’→f' uniformly in D . true/false and why
Suppose that f(z) is defined in the unit disk D such that (f(z))^2 and (f(z))^3 are analytic in D. prove or disprove that f(z) is analytic in D
True or False with explanation:-
1.The mean value theorem of a real-valued function of a real variable does not hold in general for complex-valued functions.
2.A real-valued function u in domain D cannot be analytic in D unless it is a constant function.
3.There exists a non-constant real-valued function u in open set D which is analytic in D.
4.A real-valued function u(x,y) is harmonic in D iff u(x,-y) is harmonic in D.
5.If f:D→D’ is analytic and u: D'→R is harmonic then the composition of u & f is harmonic inD.
6.{fn(z)} be a sequence of analytic function in a domain D such that fn→f uniformly inD. Then fn’→f' uniformly in D .
