The complex conjugate of a complex number z=a+bi is defined to be z^_=a-bi. (1) The conjugate matrix of a matrix A=(a_(ij)) is the matrix obtained by replacing each element a_(ij) with its complex conjugate, A^_=(a^__(ij)) (Arfken 1985, p. 210). The
Let z be a complex number satisfying, wheredenotes the complex conjugate of z . Let the imaginary part of z be nonzero Match each entry in List-I to the correct entries in List-II. The correct option is: View Solution The number of complex numbers z satisfying |z-2-i|=|z-8+i| ...
