` z - bar z = 0 ` यदि और केवल यदि

If x% of y is 150 and y% of z is 300, then the relation between x and z is : यदि y का x% 150 है और z का y% 300 है, तो x और z में क्या संबंध है ?

If z=z_0+A( bar z -( bar z _0)), w h e r eA is a constant, then prove that locus of z is a straight line.

If z=z_0+A( bar z -( bar z _0)), w h e r eA is a constant, then prove that locus of z is a straight line.

If z=z_0+A( bar z -( bar z _0)), w h e r eA is a constant, then prove that locus of z is a straight line.

If z=x+i y , then show that z bar z +2(z+ bar z )+a=0 , where a in R , represents a circle.
