The locus of a point reprersented by `x=a/2((t+1)/t),y=a/2((t-1)/1)` , where `t in R-{0},` is `x^2+y^2=a^2` (b) `x^2-y^2=a^2` `x+y=a` (d) `x-y=a`

The locus of a point represent by x=(a)/(2)((t+1)/(t)),y=(a)/(2)((t-1)/(t)) , where t=in R-{0} , is

The locus represented by x=(a)/(2)(t+(1)/(t)),y=(a)/(2)(t-(1)/(t)) is

The locus of the point x=(t^(2)-1)/(t^(2)+1),y=(2t)/(t^(2)+1)

Find the locus of a point whose coordinate are given by x = t+t^(2), y = 2t+1 , where t is variable.

If x=t+(1)/(t),y=t-(1)/(t)," where "tne0," then: "(d^(2)y)/(dx^(2))=

The locus of the moving point whose coordinates are given by (e^(t)+e^(-t),e^(t)-e^(-t)) where t is a parameter,is xy=1 (b) x+y=2x^(2)-y^(2)=4(d)x^(2)-y^(2)=2

Locus of centroid of the triangle whose vertices are (a cos t ,a s in t ), (b s in t ,-b cos t ) and (1, 0), where t is a parameter, is (3x-1)^2+(3y)^2=a^2-b^2 (3x-1)^2+(3y)^2=a^2+b^2 (3x+1)^2+(3y)^2=a^2+b^2 (3x+1)^2+(3y)^2=a^2-b^2

If x=2(t+(1)/(t)),y=3(t-(1)/(t)) then (x^(2))/(4)-(y^(2))/(9) is equal to
