The conjugate of the complex number z=x+ is denoted byz and is defined as z=x-.The objective of the problem is to show that z and z have the same modulus.The modulus of a complex number is the distance of the complex number from the origin in a complex plane. The modulus is also...
Complex Conjugate: The complex conjugate of a complex number is obtained when we want to rationalize the numerator or the denominator of a quotient containing complex numbers. The complex conjugate of {eq}a+bi {/eq} is equivalent to {eq}a-bi {/eq}. ...

To find the conjugate of the complex number z=13+4i, we will follow these steps: Step 1: Write the complex numberWe start with the complex number:z=13+4i Step 2: Multiply by the conjugate of the denominatorTo simplify z, we multiply the numerator and the denominator by the conjugate ...
Consider the complex number z=x+ The conjugate of the complex number z=x+ is denoted by z and is defined as z =x-The objective of the problem is to show that z+ z lies on the real axis.Now find z+ z. For that, substitute x+ for z and x- for z in z+z and simplify furth...
How do you find a complex number given the modulus and argument? What is the complex conjugate of the complex number 2 - 4i? Prove that if z is a complex number then \frac{1}{z}=\frac{\overline{z{|z|^2} . What is the purpose of complex numbers?
Find the set of possible values of p.[3](iii) The complex conjugate of w is denoted by w*. The complex numbers w and w* are represented in an Argand diagram by the points S and T respectively. Find, in the form |z- a| = k, the equation of the circle passing through S,...
The chapter also presents alternative form of the fundamental theorem of algebra, which states that if P(x) is a polynomial of degree n > 1, then P(x) has precisely n roots among the complex numbers when a root of multiplicity k is counted k times. The conjugate theorem extends the ...
Theconjugateof a complex number z is denoted asz¯and defined to bez¯=x−iy Two complex numbersz=x+iyandw=s+itare equal if x=s, y=t (x,y,s,t∈ R) The Argand plane: it is useful to identify the complex number x+iy with the point (x,y) inR^2. We can introduce polar...
