Answer:
Hence, the scalar projection of onto
=
, and the vector projection of
onto
=
.
Step-by-step explanation:
We have given two points and
.
Let, and
.
and we have calculate the projection of onto
.
Now,
For the calculation of projection, first we need to calculate the dot product of and
.
then, we have to calculate the magnitude of .
=
=
=
.
Now, the scalar projection of onto
=
=
and the vector projection of onto
=
=
=
Hence, the scalar projection of onto
=
, and the vector projection of
onto
=
.
