The equation of curve referred to the new axes, axes retaining their directions, and origin `(4,5)` is `X^2+Y^2=36` . Find the equation referred to th
With the given notation, we have `x=X+4,y=Y+5` or `X=x-4,Y=y-5` Therefore, the required equation is `(x-4)^2+(y-5)^2=36` or `x^2+y^2-8x-10y+5=0` which is the eqaution referred to the original axes.

Two lines are drawn at right angles, one being a tangent to `y^2=4a x` and the other `x^2=4b ydot` Then find the locus of their point of intersection.
`y=mx+(a)/(m)` (1) is a tangent to `y^(2)=4ax` and `x=m_(1)y+(b)/(m_(1))` (2) is a tangent to `x^(2)=4by`. Lines (1) and (2) are perpendicular. Therefore, `mxx(1)/(m^(1))=-1` `or" "m_(1)=-m` Let (h,k) be the point...
