Solution to Problem6



Find the cross product and the inner product between the vectors (i+j) and (i-j+k).


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);


gosh this is soooo easy.... try doing it by hand using the distributivity property for the dot and cross products. Good exercise... DO IT!
