If `cos 0 =(-3)/(5) and pi lt 0 lt (3pi)/(2) ,` find the value of `tan theta //2`

If cos theta = - 3/5 and pi lt theta lt (3pi)/2 , find the value of (sec theta - tan theta)/(cosec theta + cot theta)

If sin x =(3)/(5) " and " 0 lt x lt (pi)/(2) find the value of tan (x)/(2)

If cosx =(-1)/(3) and pi lt x lt (3pi)/(2) Find the value of cos (x/2) , tan (x/2)

If cos theta =(-5)/(13) and (pi)/(2) lt theta lt pi , find the value of sin 2 theta

If sin theta =12/13 (0 lt theta lt (pi)/(2)) and cos phi =-3/5 (pi lt phi lt (3pi)/(2)) then the value of sin (theta+ phi) will be-
