Let `a=sin10^(@), b =sin50^(@), c=sin70^(@)," then " 8abc((a+b)/(c ))((1)/(a)+(1)/(b)-(1)/(c ))` is equal to

Prove : sin 10^(@)sin50^(@)sin70^(@) = 1//8 .

Prove that 8 sin10^@.sin50^@.sin70^@=1

sin 50 ^(@) - sin 70^(@) + sin 10^(@) A)-1B)0C) sin 5^(@) D) -sin 5^(@)

If sin^(-1)a+sin^(-1)b+sin^(-1)c=pi, then a sqrt(1-a^(2))+b sqrt(1-b^(2))+c sqrt(1-c^(2)) is equal to a+b+c( b )a^(2)b^(2)c^(2)2abc(d)4abc

The value of sin 10^(@) sin 30^(@) sin 50^(@) sin 70^(@) is.............. A) 1/8 B) 1/16 C) (sqrt3)/(8) D) (sqrt3)/(16)

If sin^(-1)a+sin^(-1)b+sin^(-1)c=pi, then asqrt(1-a^2)+bsqrt(1-b^2)+csqrt(1-c^2) is equal to (a) a+b+c (b) a^2b^2c^2 (c) 2a b c (d) 4a b c

In /_ABC if cos A cos B+sin A sin B sin C=1, then the value of (sin^(2)A)/(sin^(2)B)+2(sin^(2)B)/(sin^(2)C)+(sin^(2)C)/(sin^(2)A) is equal to

In a triangle ABC,if (2(sin B-sin C))/(cos B+cos C)=(sin A)/(1-cos A) then the value of (b)/(c) is equal to

If sin^(-1)a+sin^(-1)b+sin^(-1)c=pi, then the value of ^( value of )+b sqrt((1-b^(2)))+sqrt((1-c^(2))) will be (A) 2abc(B)abc(C)(1)/(2)abc(D)(1)/(3)abc
