If `(3+2isintheta)/(1-2isintheta)` is a real number and `0ltthetalt2pi` then `theta`

If (3+2isintheta)/(3-2isintheta) is real , then theta =

If (3+2isintheta)/(1- 2isintheta) is real , then general value of theta is :

If (3+2isintheta)/(1- 2isintheta) is real , then general value of theta is :

If (1-sintheta)/(1+2isintheta) is purely imaginary then theta=

If z = (3+isintheta)/(4-icostheta) is purely real and theta in (pi/2,pi) ,then arg(sintheta + i costheta) is -

If z = (3+isintheta)/(4-icostheta) is purely real and theta in (pi/2,pi) ,then arg(sintheta + i costheta) is -

If sin theta+cos theta=1/5and 0ltthetalt2pi,then tan thetais

If sin theta+cos theta=1/5and 0ltthetalt2pi,then tan thetais
