a=3i+j c=2i+2j+2k (a) Find the equation of the plane that passes through all three points a, b, and c. (b) Compute lc- (a x where x is the cross product, is the inner product, and I is the absolute value. (c) Find the absolute value of the determinant of the matrix P e IR3*3 where its first row is c, second row a, and its third row is b. (d) Draw the parallelpiped with the given sides as a, b, and c. Relate the values in part(b) and part(c) to the parallelpiped.
