In a triangle ABC, the value of `sinA+sinB+sinC` is

If a DeltaABC , the value of sinA+sinB+sinC is

In triangle ABC , if AB=2,BC=4 and AC=5, then the value of (sinA-sinB)/(sinC) is equal to

If ABCD is a cyclic quadrilateral, then find the value of sinA + sinB -sinC - sinD

If ABC D is a cyclic quadrilateral, then find the value of sinA+sinB-sinC-sinD If A+B+C=(pi)/(2) , then find the value of tanA tanB+tanBtanC+tanC tanA

In a DeltaABC, sin A sinB sinC is

If the median of triangle ABC through A is perpendicular AB, then the value of sinA cosB + 2sinB cosA is equal to
