Now cos(A-B) is always less than or equal to one. We know that |x+y|^2= |x|^2+ |y |^2 + 2 |x | | y | cos(A-B), where A and B are arguments of x and y respectively. z1 = 0 â 4i and z2 = 2 â 3i. For Any Two Complex Numbers Z1 and Z2 and Any Two Real Numbers A, B, Find the Value of | a Z 1 â B Z 2 | 2 + | a Z 2 + B Z 1 | 2 . Similarly, the complex number z1 âz2 can be represented by the vector from (x2, y2) to (x1, y1), where z1 = x1 +iy1 and z2 = x2 +iy2. If z1,z2 are two complex numbers and such that |(z1-z2/z1+z2)|=1 and iz1=Kz2 where K â R, then the angle between z1-z2 and z1+z2 is (A) tan-1((2K/K2 We can represent sum of complex numbers as a diagonal of the parallelogram formed by them as shown in the figure below. In fact, for any complex number z, its conjugate is given by z* = Re(z) â Im(z). Given $\frac{2z_1}{3z_2}$ is an imaginary number. If z 2 + z + 1 = 0, where z is a complex number, ... A body weighing 13 kg is suspended by two strings 5 m and 12 m long, their other ends being fastened to the extremities of a rod 13 m long. First condition Im (Z1+Z2)=0, gives b+ d =0, means imaginary parts of both the numbers are additive inverse. There is a complex number such that z = z for all complex numbers z.
