If `sinA=-4/5` and `pi lt A lt (3pi)/2`, find the value of `(cosecA+cotA)/(secA-tanA)`

If sinA = -5/13 and pi lt A lt (3pi)/(2) , find the values of the following: i) sin(A/2) , ii) cos(A/2) , iii) tan(A/2)

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

If tanA = 12/5 and pi lt A lt (3pi)/(2) , find the values of the following: i) sin2A ii) cos2A iii) tan2A

If tanA=5/(12) , find the value of (sinA+cosA)secA .
