Let \(\vec{v} = \langle 2, 4, 3 \rangle\) and \(\vec{w} = \langle 5, 4, -4 \rangle\). Express the vector \(\vec{v}\) as the sum of a vector parallel to \(\vec{w}\) and a vector orthogonal to \(\vec{w}\).

We denote the vector component of \(\vec{v}\) along \(\vec{w}\) as \(\vec{p}\), so \(\vec{p} = \text{proj}_{\vec{w}}\vec{v}\).

We denote the vector component of \(\vec{v}\) orthogonal to \(\vec{w}\) as \(\vec{q}\), and have \(\vec{q} = \vec{v} - \vec{p}\), so that

\[
\vec{v} = \vec{p} + \vec{q}
\]

(a) Determine the vector component of \(\vec{v}\) along \(\vec{w}\):

\[
\vec{p} = 
\]

(b) Determine the vector component of \(\vec{v}\) orthogonal to \(\vec{w}\):

\[
\vec{q} = 
\]
