Let AB and C be the angles of `Delta ABC`, then the minimum value of `sin^2(A/2)+sin^2(B/2)+sin^2(C/2)` is (1) 1 (2) `3/4` (3) `1/2` (4) `1/4`

In a right angled triangle ABC, write the value of sin^2 A + sin^2 B+ sin^2C

ABC is a right angled triangle, then the value of sin^(2)A + sin^(2)B + sin^(2)C will be-

In a right angled triangle ABC,write the value of sin^(2)A+sin^(2)B+sin^(2)C

In Delta ABC,a=3,b=4 and c=5, then value of sin A+sin2B+sin3C 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 -
