Why can't the horizontal or vertical component equal the magnitude of the vector?

Question:

Why can't the horizontal or vertical component equal the magnitude of the vector?

Magnitude of A Vector:

For any vector (let's choose two dimensions without loss of generality), say {eq}\vec{A} = A_1 \hat{e}_1 + A_2 \hat{e}_2, {/eq}

the magnitude of this vector is given by:

{eq}|\vec{A}| = A = \sqrt{A^2_1 + A^2_2} {/eq}

Answer and Explanation:

For any vector, {eq}\vec{A}, {/eq} with two non-zero components, the magnitude is given by:

{eq}|\vec{A}| = A = \sqrt{A^2_1 + A^2_2} {/eq}

The...
