Chapter 2, Problem 232(choose chapter or problem)
[T] Assume that the magnitudes of two nonzero vectors u and v are known. The function \(f(\theta)=\|\mathbf{u}\| \quad\|\mathbf{v}\| \sin \theta\) defines the magnitude of the cross product vector \(\mathbf{u} \times \mathbf{v}\), where \(\theta \in[0, \pi]\) is the angle between u and v.
a. Graph the function f.
b. Find the absolute minimum and maximum of function f. Interpret the results.
c. If \(\|\mathbf{u}\|=5\) and \(\|\mathbf{v}\|=2\), find the angle between u and v if the magnitude of their cross product vector is equal to 9.
Text Transcription:
f(theta) = |u| |v| sin theta
u times v
theta [0, pi]
|u| = 5
|v| = 2
