TITLE: Solution to Problem6
# !b1 Problem6:
Find the cross product and the inner product between
the vectors (i+j) and (i-j+k).
!b3 SOLUTION:
Piece of cacke...
> i := [1,0,0]: j := [0,1,0]: k := [0,0,1]:
# the crossproduct is,
> crossprod( i+j, i-j+k );
[1, -1, -2]
# and the dotprod is,
> dotprod(i+j,i-j+k);
0
# gosh this is soooo easy.... try doing it by hand using the
distributivity property for the dot and cross products.
Good exercise... DO IT!
