Question

Eliminate the parameter to find a Cartesian equation of the
curve. x= squrt t+1, y=squrt t-1

Answer 1

dose any one know the answer ?

Answer 2

well are the equations

\[x = \sqrt{t + 1}...and.....y = \sqrt{t -1}\]

Answer 3

yep

Answer 4

ok... so looking at the x equation can't you say

\[x^2 -1 = t\]

then substitute that into the y equation...
