Curves - Degree (Chord and Arc Definition) - L,T,E,M,Lc,PT,, PC

Hi,
If you are given with the degree, angle of intersection and Station of PI, how to find the L(length of curve), T(Tangent length), E(External ordinate), M, Lc(Length of chord), PT(Point of tangency) station, PC(Point of Curvature) station. The formulae and example is given in the following images.

Example has three parts, each part is a different question in itself.





Thanks!
