Intro to parametric curves

1. Homework Statement
Identify and sketch the curve represented by the parametric equations:

[tex]x=1+cost[/tex]
[tex]y=1+sin^2t[/tex]

2. Homework Equations
3. The Attempt at a Solution
I have to isolate t in one of these equations and sub whatever t equals into the other equation right? So how do I get rid of the cos on the left here? I'm not so quick with this trig stuff :?

[tex]cost=x-1[/tex]
Thanks.

cos(t)=x-1. Now just remember cos(t)^2+sin(t)^2=1.
