`triangleABC` में सिद्ध कीजिए कि
`2 (a sin^(2)""(C)/(2) +csin^(2)""(A)/(2)) = c +a -b`

Prove that, 2(asin^(2)((C)/(2))+csin^(2)((A)/(2)))=c+a-b

सिद्ध कीजिए कि 2tan^(-1)sqrt((b)/(a))=cos^(-1)((a-b)/(a+b))

In any o+ABC, prove that: 2{a sin^(2)(C)/(2)+csin^(2)(A)/(2)}=a+c-b

In a DeltaABC,2asin^(2)C/2+2csin^(2)A/2=

In a DeltaABC,2asin^(2)C/2+2csin^(2)A/2=

Prove that, (c+a-b)/(2)=a sin^(2)(C/2)+csin^(2)(A/2)

Consider a triangle ABC satisfying 2asin^(2)((C)/(2))+2csin^(2)((A)/(2))=2a+2c-3b Sin A , sin B , sin C are in

Consider a triangle ABC satisfying 2asin^(2)((C)/(2))+2csin^(2)((A)/(2))=2a+2c-3b The sides of the triangle are in

In triangle ABC , with the usual notations , prove that 2{a sin^(2).(C)/(2)+csin^2.(A)/(2)}=a+c-b

In triangleABC, 2(b-c)cos^(2)((A)/(2))=
