Find an equation of the tangent(s) to the curve at a given point. Then graph the curve and the tangent(s). x = 6sin(t), y = t^2 + t; (0,0) How do I do this without the value of t? I don't see a way to eliminate the parameter.

Thank you!

I don't quite understand Cartesian equations. I am told to Eliminate the parameter to find a cartesian equation of the curve. X= 3 - 4t, y= 2 - 3t there is no inequality I don't understand what I am trying to find.
