Consider the parameterization of the unit circle given by x=cos(3t2−t), y=sin(3t2−t) for t in (−[infinity],[infinity]). describe in words and sketch how the circle is traced out, and use this to answer the following questions. (a) when is the parameterization tracing the circle out in a clockwise direction?

Triangle jkl is transformed to create triangle j'k'l'. the angles in both triangles are shown. j = 90° j' = 90° k = 65° k' = 65° l = 25° l' = 25° which statement is true about this transformation? it is a rigid transformation because the pre-image and image have the same corresponding angle measures. it is not a rigid transformation because the corresponding side lengths are not equal. it can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures. it can be a rigid or a nonrigid transformation because a pair of corresponding angles measures 90°.
