[" In "Delta ABC" if the angle "A,B,C" are in A.P.then "],[qquad (a+c)/(sqrt(a^(2)-ac+c^(2)))=]

In Delta ABC if the angle A,B,C are in A.P.then (a+c)/(sqrt(a^(2)-ac+c^(2)))=

In a Delta ABC ,if angle, A,B,C are in A.P then (a+c)/(sqrt(a^(2)-ac+c^(2) 1.cos((A-C)/(2)) 2. 2cos((A-C)/(2)) 3. 2sin((A-C) 4. 2cos(A+C)

In Delta ABC , if A,B,C are in A.P then (a+c)/sqrt(a^2-ac+c^2)=

In Delta ABC , if A,B , C are in A.P. The (a+c)/( sqrt(a^(2) -ac + c^(2))

In a triangle,if the angles A,B, and C are in A.P.show that 2cos(1)/(2)(A-C)=(a+c)/(sqrt(a^(2)-ac+c^(2)))

If the angle A,B,C of a Delta ABC are in A.P then :-

In triangle ABC if the angles A,B and C be in A.P. then show that 2cos ((A-C)/2)=(a+c)/sqrt(a^2-ac+c^2)

In Delta ABC, if a,b,c are in A.P.then (tan A)/(2),(tan B)/(2),(tan C)/(2) are in

If a,b,c are in A.P.then ((a-c)^(2))/((b^(2)-ac)=)
