Application of trignometry in real life.

If x+y+z=xyz , prove by trignometry that: (2x)/(1-x^(2))+(2y)/(1-y^(2))+(2z)/(1-z^(2))=(2x)/(1-x^(2)).(2y)/(1-y^(2)).(2z)/(1-z^(2))

The value of the determinant |(-1,1,1),(1,-1,1),(1,1,-1)| is equal to

Prove that |[1+a,1,1,1],[1,1+a,1,1],[1,1,1+a,1],[1,1,1,1+a]|=a^(3)(a+4)

The simplest value of ((1+(1)/(2))(1+(1)/(3))(1+(1)/(4))....(1+(1)/(50)))/((1-(1)/(2))(1-(1)/(3))(1-(1)/(4)).....(1-(1)/(50))) is
