For any `triangleABC`, the value of determinant `|[sin^2A,cotA,1],[sin^2B,cotB,1],[sin^2C,cotC,1]|` is:

If A+B+C =pi , then the value of determinant |{:(sin^2A,cotA,1),(sin^2B,cotB,1),(sin^2C,cotC,1):}| is equal to

For any "Delta"A B C the value of determinant |sin^2\ \ A cot A1sin^2B cot B1sin^2\ \ C cot C1| is equal to- s in A s in B s in C b. 1 c. 0 d. s in A+s in B+s in C

For any "Delta"A B C the value of determinant |sin^2\ \ A cot A1sin^2B cot B1sin^2\ \ C cot C1| is equal to- s in A s in B s in C b. 1 c. 0 d. s in A+s in B+s in C

If A+B+C=pi , then the value of determinant |{:(sin^(2)A, cotA,1),(sin^(2)B,cotB,1),(sin^(2)C,cot C,1):}| is equal to

If A+B+C = pi , prove that [[sin^2A,cotA,1],[sin^2B,cotB,1],[sin^2C,cotC,1]] =0

If A+B+C=pi then |(sin^(2)A,cotA,1),(sin^(2)B,cotB,1),(sin^(2)C,cotC,1)|=

If A+B+C= pi and Delta = |{:(sin^2A,cotA,1),(sin^2B,cotB,1),(sin^2C,cotC,1):}| , find Delta +5 .
