Let z=x+iy𝑧=𝑥+𝑖𝑦 and a point P𝑃 represent z𝑧 in the Argand plane. If the real part of z−1z+i𝑧-1𝑧+𝑖 is 1,1, then a point that lies on the locus of P𝑃 is
Question
Solution 1
The given condition is that the real part of (z - 1)/(z + i) is 1.
Let's write z as x + iy and substitute it into the equation:
Real[(x + iy - 1) / (x + iy + i)] = 1
This simplifies to:
Real[((x - 1) + iy) / (x + (y + 1)i)] = 1
The real part of a complex number a + bi is a. So, we can separate Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
