Solved: Given a curve C: r(t), find a tangent vector r' (t), a unit tangent vector u'
Chapter 9, Problem 9.1.170(choose chapter or problem)
Given a curve C: r(t). find a tangent vector r’(t), a unit tangent vector u'(t), and the tangent of C at P. Sketch the curve and the tangent.
\(\mathbf{r}(t)=[\cosh t, \quad \sinh t], \quad P:\left(\frac{5}{3}, \frac{4}{3}\right)\)
Text Transcription:
r(t)=[cosh t, sinh t], P:(5/3, 4/3)
