Consider a line `abarz +baralphaz+ibeta = 0` such that `-alpha/bar(alpha)=lambda(1+i), lambda in R^+`, then the angle made by line with real axis is `pi/k` , then k is

Consider a line abar(z)+bar(alpha)z+i beta=0 such that -(alpha)/(bar(alpha))=lambda(1+i),lambda in R^(+), then the angle made by line with real axis is (pi)/(k), then k is

If alpha is a complex number and x^(2)+alpha x+bar(alpha)=0 has a real root lambda then lambda=

Consider the equaiton of line abarz + abarz+ abarz + b=0 , where b is a real parameter and a is fixed non-zero complex number. The intercept of line on real axis is given by

Assertion (A) : If a line make angles 45^(@), 45^(@) with the x and y axis repectively then it makes angle 60^(@) with z - axis Reason (R ) : If alpha,beta,lambda are the angle made by a line with the coordinate axes then cos^(2) alpha + cos^(2)beta + cos^(2) lambda = 1

Consider the equaiton of line abarz + abarz+ abarz + b=0 , where b is a real parameter and a is fixed non-zero complex number. The intercept of line on imaginary axis is given by
