Given z=f(x)+ig(x)w h e r ef,g:(0,1) --> (0,1) are real valued functions. Then which of the following does not hold good? z=1/(1-i x)+i1/(1+i x) b. z=1/(1+i x)+i1/(1-i x) c. z=1/(1+i x)+i1/(1+i x) d. z=1/(1-i x)+i1/(1-i x)

Let f(x) be a real valued function not identically zero, which satisfied the following conditions I. f(x + y^(2n + 1)) = f(x) + (f(y))^(2n+1), n in N, x, y are any real numbers. II. f'(0) ge 0 The value of f(1), is

Let f_1 (x,y)-=ax^2+2hxy+by^2=0 and let f_(i+1) (x,y)=0 denote the equation of the bisectors of f_i (x,y)=0 for all i=1,2,3,….. If f_1 (x,y)=0 repersents the equation of a pair of perpendicular lines , then f_3(x,y) =0 is same as
