i've tried, generating a set and points and just sketching it and tried using the ezsurf/surf function to do it... but both ways failed. Does completing the derivative at t=0 the same as n=0?

So I have this system of equations: \binom{x_{n+1}}{y_{n+1}}=\begin{pmatrix}e^{r} & 0 \\ 0 & e^{-r} \end{pmatrix}\begin{pmatrix}cos(\phi+I_{n}) & -sin(\phi+I_{n}) \\ sin(\phi+I_{n}) & cos(\phi+I_{n}) \end{pmatrix}\begin{pmatrix}x_{n}\\ y_{n} \end{pmatrix} where I_{n}=x_{n}^2+y_{n}^2...

Ahhh okay, so then i just do the partial of each entry in the matrix to check if the det=1?

I'm pretty for q1 you need to use a continuous paying annuity formula which is PV=PMT*((1-v^n )/delta) where delta=ln(1+r) and v=1/(1+r)
