In a `Delta ABC, c cos ^(2)""(A)/(2) + a cos ^(2) ""(C ) /(2)=(3b)/(2),` then

If in a triangle ABC, b cos ^(2) "" A/2 + a cos ^(2) "" B/2 = (3c)/(2), then

If in a Delta ABCa cos^(2)((c)/(2))+c cos^(2)((A)/(2))=(3b)/(2) then the sides a,b and c

If in a triangle ABC,b cos^(2)((A)/(2))+a cos^(2)((B)/(2))=(3)/(2)c then a,c,b are:

In a triangle ABC,bc cos^(2)(A)/(2)+ca cos^(2)(B)/(2)+ab cos^(2)(C)/(2)=

In Delta ABC,b(cos^(2)C)/(2)+c(cos^(2)B)/(2)=

Delta ABC, cos ((B + 2C + 3A) / (2)) + cos ((AB) / (2)) =

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

In any Delta ABC, prove that: (cos^(2)((A)/(2)))/(a)+(cos^(2)((B)/(2)))/(b)+(cos^(2)((c)/(2)))/(c)=(s^(3))/(abc)
