A straight line through the vertex P of a triangle PQR intersects the side QR at the point S and the circuecirele of the triangle PQR at the point T. If S is not the centre of the circumeircle,then

A straight line through the vertex P of a triangle P Q R intersects the side P Q at the point S and the circumcircle of the triangle P Q R at the point Tdot If S is not the center of the circumcircle, then 1/(P S)+1/(S T) 2/(sqrt(Q S x S R)) 1/(P S)+1/(S T) 4/(Q R)

A straight line through the vertex P of a triangle P Q R intersects the side Q R at the points S and the cicumcircle of the triangle P Q R at the point Tdot If S is not the center of the circumcircle, then 1/(P S)+1/(S T) 2/(sqrt(Q SxxS R)) 1/(P S)+1/(S T) 4/(Q R)
