A vector uuu has a magnitude of 202020 and makes an angle of 315∘315^{\(\circ\)} with the positive xx-axis. Write the vector uuu in terms of i\(\mathbf{i}\) and j\(\mathbf{j}\).

A vector $u$ has a magnitude of $20$ and makes an angle of $315 raised to the composed with power$ with the positive $x$ -axis. Write the vector $u$ in terms of $i$ and $j$ .
