Homework Statement
Given [tex]r(t) = x(t)\textbf{i} + y(t)\textbf{j}[/tex] and
[tex]\int_0^t \left\|\frac{dr}{dt}\right\| d\tau = t.[/tex]
find, if possible, a closed form expression for x(t) and y(t).
Homework Equations
The Attempt at a Solution
I started by applying the fundamental theorem of calculus
[tex]\left\|\frac{dr}{dt}\right\|=1[/tex]
then evaluated and simplified and got
[tex]x(t)^2 + y(t)^2 = 1.[/tex]
Is it possible to continue from here?
