    let z=x+yi so mod(z-u)= square root of [(x+0.4)^2 + (y-2.2)^2] ---> 1 and mod of u=square root of 5 ---> 2 On equating 1 and 2 and then squaring on both sides..v get:- (x+0.4)^2 + (y-2.2)^2 = 5 this is lyk an equation of a circle wid centre (-0.4, 2.2) and radius= square root of 5 idk...how...

    Q.6)i) (consider cos(theta)=cosX) L.H.S= 2cos^2(2X) -1 + 4[2cos^2 (X) -1] =2[2cos^2(X) -1]^2 + 8cos^2(X) -5 on expanding and simplyfying furthr...u get R.H.S Q.7)iii) sinX= 2/(x+2) so 2/sinX=(x+2) so 2cosecX=(x+2) hence cosecX=(x+2)/2 which gives cosecX=(x/2)+1 Hope dis...
