Unformatted text preview: a = ? NO. In fact for any vector a it is true that a × a = 5.  v × w  = √ 122 6. Find the area of the triangle with vertices (0 , , 0), (0 , , 1) and (0 , 1 , 2) ANS= 1 / 2 7. Find  triple product  = 0 Thus the vectors are coplanar. 8. a) h3 / √ 35 , 5 / √ 35 ,1 / √ 35 i b) Not parallel (clear). If we equate x’s and y’s we can get s = 0 and t = 0 to solve the system of 2 × 2 but these values of the parameters don’t make the z’s equal, so they don’t intersect. Thus L 1 and L 2 ARE skew....
