If `A+B+C=pi,` show that `|(sin^2A,sinAcosA,cos^2A),(sin^2B,sinBcosB,cos^2B),(sin^2C,sinCcosC,cos^2C)|=-sin(A-B)sin(B-C)sin(C-A)`

(sin^(2)A-sin^(2)B)/(sinAcosA-sinBcosB)=?

If A+B+C=pi, prove that sin^(2)A+sin^(2)B+sin^(2)C=2(1+cos A cos B cos C)

If A+B+C=pi , prove that sin 2A+sin 2B-sin 2C=4 cos A cos B sin C

If A+B+C=pi then prove that sin2A-sin2B+sin2C=4cos A sin B cos C

If A+B+C=pi , prove that sin 2A-sin 2B+sin 2C=4cos Asin B cos C.

If A+B+C= (pi)/(2) , then show that sin 2A+sin 2B +sin 2C=4 cos A cos B cos C
