I would like to get the plot of the parametric curve $(x1(t),x2(t)$ for $t$ in $[0,1]$.

x1sol=vector([-cos(ts),sin(ts)])*exp(ts/2)

x2sol=vector([sin(ts),cos(ts)])*exp(-ts)

x11 = x1sol[0]

x12 = x1sol[1]

show(plot(x11(ts),x12(ts),(ts,0,1)))

I get the error: TypeError: unable to simplify to float approximation

I would like to avoid formulation as :

def x1(t): ....

I would like to get the plot of the parametric curve $(x1(t),x2(t)$ for $t$ in $[0,1]$.

x11 = x1sol[0]

x12 = x1sol[1]
