Area of the triangle formed by (x,y+z),(y,z+x),(z,x+y) is

The repeated factor of the determinant |(y +z,x,y),(z +x,z,x),(x +y,y,z)| , is

Determinant form of (x-y)(y-z)(z-x)

What is the determinant of the matrix ({:(x,y,y+z),(z,x,z+x),(y,z,x+y):}) ?

What is the area of the triangle having side lengths ( y )/( z) + ( z)/( x) , ( z)/( x) + ( x )/( y ), ( x )/( y ) + ( y )/( z) ?

If x, y, z be three sides of a triangle, prove that xyzge(y+z-x)(z+x-y)(x+y-z) .

the degree measure of three angles if a triangle are x,y and z If z=(x+y)/2 then find the value of z

If A = {x, y, z}, then the relation R={(x,x),(y,y),(z,z),(z,x),(z,y)} , is

The value of |(x +y,y+z,z+x),(x,y,z),(x -y,y-z,z-x)| is euqal to
