If a,b,c are sides of an equilateral triangle, the value of `|[a,b,c],[b,c,a],[c,a,b]|` is

If a,b,c are sides of a scalene triangle,then value of |abcbcacab| is (a)positive (b) negative (c)non-positive (d) non-negative

Suppose a,b,c are sides of a scalene triangle. Let Delta=|(a,b,c),(b,c,a),(c,a,b)| Then

If a, b,c are the lengths of the sides of triangle , then

If a,b,c are the sides of a triangle,then the minimum value of (a)/(b+c-a)+(b)/(c+a-b)+(c)/(a+b-c) is equal to (a)3(b)6(c)9(d)12

If a,b and c are the side of a triangle,then the minimum value of (2a)/(b+c-a)+(2b)/(c+a-b)+(2c)/(a+b-c) is 3 (b) 9(c)6(d)1

If a, b, c are sides of the triangle ABC and |(1,a, b),(1,c,a),(1,b,c)|=0 , then the value of cos 2A+cos 2B+cos 2C is equal to

If a, b, c are the sides of a triangle ABC and |(1,a,b),(1,c,a),(1,b,c)|=0, then the value of cos^2 A + cos^2 B +cos^2 C is equal to
