If `Z=ilog(2-sqrt(3))`,then `cos(Z)`=

If Z=i log(2-sqrt(3)), then cos(Z)=

If z=i log(2-sqrt(-3)), then cos z=

lf z = ilog(2-sqrt(3)) , then cos z =

lf z = ilog(2-sqrt(3)) , then cos z =

If z = ilog(2-sqrt3) , then cosz =

Assertion (A) : If z = ilog (2 - sqrt3) then cos z= 2 Reason (R) : cos h theta = (e^(itheta ) + e^(itheta))/(2)

If z=ilog_e(2-sqrt3) then the value of cosz

If z=ilog_(e)(2-sqrt(3)),"where"i=sqrt(-1) then the cos z is equal to
