The product of the sines of the angles of a triangle is `p` and the product of their cosines is `qdot` Show that the tangents of the angles are the roots of the equation `q x^3-p x^2+(1+q)x-p=0.`

A

`qx^(2)-px^(2)+(1-x) x-p =0`

B

` qx^(3)-px^(2)-(1-q) x-p =0`

C

`qx^(3)-px^(2)+(1+q)x-p =0`

D

None of these
