i have 2 questions

- i have a parametric plot :
i would like to get the first and the last point of this polar curve
in the specs of "linspace" (https://docs.scipy.org/doc/numpy/reference/generated/numpy.linspace.html <https://docs.scipy.org/doc/numpy/reference/generated/numpy.linspace.html>) i dont see how to do that automatically
is there something simple like "first(X)" and "last(X)"

- i have a function :
rotation(vect,theta) which takes vect=[a,b] and theta-rotates it by a matrix
how to use this function or such a function to rotate a tuple (X,Y) with X,Y as described above in this message ?
