For a complex number z =x + iy, the argument theta satisfies - answer-tantheta = y/x
For a complex number z with |z| = r and arg(z) = theta, the modulus-argument form of z is - answer-z = r(cos(theta) + isin(theta))
For any complex number z = a + bi, the complex conjugate of the number is defined as - answer-z* = a - bi
For any two complex numbers z1 and z1, arg(z1z2) = - answer-arg(z1) + arg(z2)
For any two complex numbers z1 and z2, |z1/z2| = - answer-|z1|/|z2|
For any two compl...
