" 3.If "ABCD" is a cyclic quadrilateral,then find the value of "sin A+sin B-sin C-sin D

If ABCD be a cyclic quadrilateral,-prove that sin A+ sin B -sin C -sin D = 0

In a triangle ABC, the value of sin A+sin B+sin C is

If ABCD is a cyclic quadrilateral then show that i) cos A + cos B + cos C + cos D = 0 ii) sin A + sin B = sin C + sin D

If A, B, C, D are angles of a cyclic quadrilateral then P.T sin A - sin C = sin D - sin B .

If A,B,C are the angles of a triangle, find the maximum values of : sin A sin B sin C

If A,B,C,D be the angles of a quadrilateral , what is the value of (sin(A+B))/(sin (C+D)) +(cos(C+D))/(cos (A+B))

In any DeltaABC, find sin A+sin B+ sin C.

In any DeltaABC, find sin A+sin B+ sin C.

In any quadrilateral ABCD, show that: cosA cosB-cosC cosD="sin"A "sin"B-"sin"C "sin"D.

Statement I if A,B,C,D are angles of a cyclic quadrilateral then sum sin A=0. Statement II If A, B, C, D are angles of cyclic quadrilateral then, sum cos A=0.
