4. decide if the following sets of vectors are linearly independent:

(b)(1 +t); (1 +t^2); (1-t)

also,

First work with stencil one. use a combination of reflections, rotations, and translations to see whether stencil one will overlap with the original pattern. list the sequence of rigid transformations you used in your attempt, noting the type of transformation, the direction, the coordinates, and the displacement in
