1. Sketch the curve with vector function r(t} : ti l coalartlj for [l i t g 2 (note that this sketch should be in 2-dimensions). 2. On the sketch, without evaluating them. include T and N at the point when t : 1 with arrows for T and N pointing in the correct direction. 3. Find r'(t) and r\"(t). 4. For the vector function in part 1, nd T and the tangential component of acceleration (1T. both when t : 1. be or embed your response in the Discussion text box. o Remember. your response should be short and to the point and NOT more than a half a _..._.._...
