In `triangleABC` if `2c cos^2(A/2)+2acos^2(C/2)-3b=0` prove that a, b, c are in A.P.

In Delta ABC if 2c cos^(2)((A)/(2))+2a cos^(2)((C)/(2))-3b=0. Prove that a,b,c are in AP

In triangleABC if acos^2(C/2)+c cos^2(A/2)=3b/2 then show that a,b,c are in A.P

In a Delta ABC, c cos^2 A/2+a cos^2C/2=(3b)/(2) then show a,b,c are in A.P

In a Delta ABC, c cos^2 A/2+a cos^2C/2=(3b)/(2) then show a,b,c are in A.P

If in a triangle A B C ,acos^2(C/2)+ c cos^2(A/2)=(3b)/2, then the sides a ,b ,a n dc are in A.P. b. are in G.P. c. are in H.P. d. satisfy a+b=cdot

If acos^(2).(C)/(2)+c"cos"^(2)(A)/(2)=(3b)/(2), then show that a, b , c are in A.P

In /_\ABC if acos^2(frac{C}{2})+c cos^2(frac{A}{2}) = frac{3b}{2} then prove that a,b,c are in A.P.
