parabola

The angle between tangent drawn from the point (3,4) to the parabola y² -2y+4x=0 is

(y-1)²+4(x-1/4)=0

shift coordinates so dat origin comes at (1,1/4)

so question becomes tangent length from (2,3.75) to parabola y²+4x=0

if you still make more standard parabola... y²=4x

then it will be lenth of tangent from (-1,1/4) to parabola y²=4x
