`Delta ABC` में सिद्ध कीजिए कि - `(cos A)/(b cos C +c cos B )+(cos B )/(c cos A+a cos C)+(cos C)/(a cos B +b cos A)=(a^2+b^2+c^2)/(2abc)`

In any DeltaABC , prove that : (cos A)/(b cos C + c cos B) + (cos B)/(c cos A + a cos C) + (cos C)/(a cos B + b cos A) = (a^2 + b^2 + c^2)/(2abc)

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

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

In a Delta ABC if (cos A)/(b cos C+c cos B)+(cos B)/(c cos A+a cos C)+(cos C)/(a cos B+b cos A)=(a^(2)+b^(2)+c^(2))/(Kabc) then K^(k) is equal to

(cos A)/(a)+(cos B)/(b)+(cos C)/(c)=(a^(2)+b^(2)+c^(2))/(2abc)

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

In Delta ABC, prove that :(c-b cos A)/(b-c cos A)=(cos B)/(cos C)

In a Delta ABC,(cos A cos B)/(ab)+(cos B cos C)/(bc)+(cos C cos A)/(ca) is equal to

For any triangle ABC, prove that (cos A)/(a)+(cos B)/(b)+(cos C)/(c)=(a^(2)+b^(2)+c^(2))/(2abc)
