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 !ABC , if 2b = a + c and A - C = 90^(@) , then sin B equals

In Delta ABC, if sin^(4)A sin B sin C=1-cos B cos C then triangle is necessarily

In /_\ABC if C = 90^@ then prove that sin(A-B) = frac{a^2-b^2}{a^2+b^2}
