(choose chapter or problem)

In Exercises 21-24, find the angle \(\theta\) between the vectors

(a) in radians and

(b) in degrees.

\(\mathbf{u}=5[\cos (3 \pi / 4) \mathbf{i}+\sin (3 \pi / 4) \mathbf{j}]\)

\(\mathbf{v}=2[\cos (2 \pi / 3) \mathbf{i}+\sin (2 \pi / 3) \mathbf{j}]\)

Text Transcription:

theta

u=5[cos (3 \pi / 4) i+sin (3 pi / 4) j]

v=2[cos (2 pi / 3) i+sin (2 pi / 3) j]
