2017-10-05 17:20:34 +0200	commented question	convert parametric equations to a normal one I have edited my question, hope it is clearer now. I mean "normal" to be something like a Conic Curve equation like ellipse is `x^2/a^2 + y^2/b^2 = 1`

2017-10-04 18:48:52 +0200	asked a question	convert parametric equations to a normal one I solved my problem into parametric equations as shown below: `x == 3/4sqrt(2m^2 + 2)m/(m^2 + 1), y == 1/4sqrt(2*m^2 + 2)/(m^2 + 1)` But I meet difficult on how to convert into a normal one, I want to get an equation with `x, y` only. For another general description: is there any function will help solve parametric equations into a normal one like solve: `x == cos(theta), y == sin(theta)` into `x ^ 2 + y ^ 2 == 1`. I learned how to solve it with my pen, but I want a solution with Sage code. Thanks.
