(a) Sketch and identify the curve defined by the parametric equations x=t2-2t, y=t+1 (tЄR) (b) What curve is represented by the given parametric equations? x = sin 2t " y = cos 2t (0 <t<2T) (c) Convert the point (2, π/3) from polar to Cartesian coordinates. (d) Determine the equation of the tangent line to r = 3+ 8 sin(0) at 0 =
