Next week we will begin the second last unit of work for the course- Vector Calculus. It builds upon the skills you developed the Vector unit (Chapter 2) we did at the start of the year. These skills are now applied to Kinematics via calculus. Sounds fun eh?
The complete solutions to Ex 12A and 12 B have now been posted to the Specialist Maths Wiki (see column on your left for the link).
