If P(t^(2),2t),Q((1)/(t^(2)),-(2)/(t)) and S(1,0) be any three points,find the value of ((1)/(SP)+(1)/(SQ))

If P(t^(2),2t),Q((1)/(t^(2)),-(2)/(t)) and S(1,0) be any three points,find the value of ((1)/(SP)+(1)/(SQ))

if P(t^(2),-2t) and Q((1)/(t^(2)),-(2)/(t)) and S(1,0) be any three points,find the value of ((1)/(SP)+(1)/(SQ))

If P and Q are two points whose coordinates are (at^(2),2at) and ((a)/(t^(2)),(2a)/(t)) respectively and s is the point (a,0). Show that (1)/(SP)+(1)/(sQ) is independent of t.

If P and Q are two points whose coordinates are (at^(2),2at) and ((a)/(t^(2)),(-2a)/(t)) respectively and s is the point (a,0), show that (1)/(SP)+(1)/(SQ) is independent of t

If A = (t^2,2t) and B = (1/t^2,-2/t) and S = (1,0), then show that 1/(SA)+1/(SB)=1

If the points : A(at_(1)^(2),2at_(1)),B(at_(2)^(2),2at_(2)) and C(a,0) are collinear,then t_(1)t_(2) are equal to

The points (a t_1^2, 2 a t_1),(a t_2^2, 2a t_2) and (a ,0) will be collinear, if

The three distinct point A(t_(1)^(2),2t_(1)),B(t_(2)^(2),2t_(2)) and C(0,1) are collinear,if

If the points (2,0)(3,2)(5,4) and (t,0) are concylic, show that t=2 or 17.
