Q. Find the midpoint m of z1=(7+8i) and z2=(8−7i).Express your answer in rectangular form.m=□
Concept of finding midpoint: Understand the concept of finding the midpoint of two complex numbers. The midpoint m of two complex numbers z1 and z2 is given by the average of their real parts and the average of their imaginary parts. m = \frac{{\text{Re}(z_1) + \text{Re}(z_2)}}{\(2\)} + \frac{{\text{Im}(z_1) + \text{Im}(z_2)}}{\(2\)}i
Identifying real and imaginary parts: Identify the real and imaginary parts of \(z_1 and z2. For z1=7+8i, the real part Re(z1) is 7 and the imaginary part Im(z1) is 8. For z2=8−7i, the real part Re(z2) is 8 and the imaginary part z20 is z21.
Calculating average of real parts: Calculate the average of the real parts of z1 and z2.2Re(z1)+Re(z2)=27+8=215=7.5
Calculating average of imaginary parts: Calculate the average of the imaginary parts of z1 and z2.2Im(z1)+Im(z2)=28−7=21=0.5
Combining averages to find midpoint: Combine the averages to find the midpoint m in rectangular form.m=7.5+0.5i
