?Show that vectors \(\mathbf{a}(t)=\langle\cos t, \sin t\rangle\) and
Chapter 2, Problem 24(choose chapter or problem)
Show that vectors \(\mathbf{a}(t)=\langle\cos t, \sin t\rangle\) and \(\mathbf{a}(x)=\left\langle x, \sqrt{1-x^{2}}\right\rangle\) are opposite for x = r and \(t=\pi+2 k \pi\), where k is an integer.
Text Transcription:
a(t) = langle cos t, sin t rangle
a(x) = langle x, sqrt 1 - x^2 rangle
t = pi + 2k pi
