`(x^(2)+y)^(17)=x^(8)y^(13)`

if (x^(2)+y^(2))/(x^(2)-y^(2))=(17)/(8) then find the value of x:y

If (x^(2)+y^(2))/(x^(2)-y^(2))=17/(8) , using the properties of proportion find the value of : (i) x : y

If (x^(2)+y^(2))/(x^(2)-y^(2))=17/(8) , using the properties of proportion find the value of : (ii) (x^(3)+y^(3))/(x^(3)-y^(3))

The locus of a point P ,so that the join of (-5,-1) and (3,2) subtend,a right angle at P is x^(2)+y^(2)+2x-3y-13=0 x^2+y^(2)+2x-3y-17=0 x^(2)+y^(2)+2x-y-17=0 x^(2)+y^(2)+4x-2y+1=0

The locus of a point "P" ,if the join of the points (2,3) and (-1,5) subtends right angle at "P" is x^(2)+y^(2)-x-8y+13=0 x^(2)-y^(2)-x+8y+3=0 x^(2)+y^(2)-4x-4y=0,(x,y)!=(0,4)&(4,0) x^(2)+y^(2)-x-8y+13=0,(x,y)!=(2,3)&(-1,5)

If sin17^(@)=(x)/(y) then prove that sec17^(@)-sin73^(@)=(x^(2))/(ysqrt(y^(2)-x^(2)))
