Perpendicular Vectors Consider the vector-valued function Show that and are always
Chapter 12, Problem 77(choose chapter or problem)
Perpendicular Vectors Consider the vector-valued function \(\mathbf{r}(t)=\left(e^{t} \sin t\right) \mathbf{i}+\left(e^{t} \cos t\right) \mathbf{j}\). Show that r(t) and r’(t) are always perpendicular to each other.
Text Transcription:
r(t)=(e^t sin t)i+(e^t cos t)j
