In a `Delta ABC " if " |(1,a,b),(1,c,a),(1,b,c)| =0`, then `sin^(2) A + sin^(2) B + sin^(2) C` is

If for a triangle ABC, |(1,a,b),(1,c,a),(1,b,c)|=0 then the value of sin^(2)A+sin^(2)B+sin^(2)C is -

In a triangle ABC, with usual notations, if |[1,a,b] , [1,c,a] , [1,b,c]|=0 then 4sin^2A+24sin^2B+36sin^2C=

Let a , b and c detnote the sides BC,CA and AB respectively of triangle ABC . If |[1,a, b],[1,c, a],[1,b ,c]|=0 . find the value of sin^2A+sin^2B+sin^2C

Let a , band c detnote the sides BC,CA andAB respectively of triangle ABC. If |[1,a, b],[1,c, a],[1,b ,c]|=0. find the value of sin^2A+sin^2B+sin^2C

In Delta ABC if a=2,b=sqrt(6) and c=sqrt(3)+1, then sin^(2)C-sin^(2)A

In Delta ABC , 2ac sin ""( 1)/(2) (A-B+C)=

In a /_ABC, if |[1,1,1,1][1+sin A,1+sin B,1+sin Csin A+sin^(2)A,sin B+sin^(2)B,sin C+sin^(2)C]|= ,then prove that /_ABC is an isosceles triangle.

In a Delta ABC " if " a^(2) sin (B - C) + b^(2) sin (C - A) + c^(2) sin (A - B) = 0 , then triangle is

In Delta ABC , if sin^(2)A + sin^(2)B = sin^(2)C , then show that a^(2) + b^(2) = c^(2) .
