" If the expression "(sin(x/2)+cos(x/2)+i tan x)/(1+2i sin(x/2))" is real,then the set all possible values of xis "

If the expression (sin(x/2)+cos(x/2)-i tan(x/2))/(1+2isin(x/2)) is real, the find the set of al possible values of x

If the expression ([s in(x/2)+cos(x/2)-i t a n(x)])/([1+2is in(x/2)]) is real, then the set of all possible values of x is.........

If the expression ([sin((x)/(2))+cos((x)/(2))-i tan(x)])/([1+2i sin((x)/(2))]) is real,then the set of all possible values of x is.......

Find the general value of x if the expression (sin ""(x)/(2) + cos"" (x)/(2) + itan x)/( 1 + 2isin "" (x)/(2)) is real .

find the value of expression (sin2x)/(1+cos2x) is:

If the complex numbers sin x+i cos2x and cos x-i sin2x are conjugate to each other then the set of values of x=

I=int(sin^(2)x-cos^(2)x)/(sin^(2)x*cos^(2)x)dx

Find real x such that (3+2i sin x)/(1-2i sin x) is purely real.

Simplify tan^(-1)((cos(x/2)+sin(x/2))/(cos(x/2)-sin(x/2)))
