1. On Parametrization:
Show that a half circle in the upper half plane with radius R and centered at origin can
be parametrized in various ways as given below:
a. x(t) = R cost, y(t) = R sint; where 0<t<n
b. x(t) = t, y(t) = √R²-t²; where - R < t < R
c. x(t) = R(2t - 1), y(t) = 2R√t-t²; where0 < t < 1
