Consider the parametric curve x = t +ln t , y = tln t , where 0 < t < ∞ . Find dy/dx and d 2 y/dx 2 . Find where the curve is increasing, decreasing, concave up, or concave down. Sketch the curve. 6 If helpful, you may use any of these formulas in any of the test questions. sin 2 x = 1 2 ± 1cos 2 x ² cos 2 x = 1 2 ± 1 + cos 2 x ² Z 1 1 + x 2 dx = ?
