Solved: Prove that and are unit vectors for any angle

Chapter 10, Problem 101

(choose chapter or problem)

(a) Use a graphing utility to graph the curve given by

\(x=\frac{1-t^2}{1+t^2},\ \ \ y=\frac{2t}{1+t^2},\ \ \  -20\ \leq\ t\ \leq\ 20\).

(b) Describe the graph and confirm your result analytically.

(c) Discuss the speed at which the curve is traced as t increases from -20 to 20.

Text Transcription:

x=1-t^2 / 1+t^2 , y=2t / 1+t^2 , -20 leq t leq 20
