Overview
Trigonometry deals with the relationship between the angles and sides of a triangle. We will learn about trigonometric ratios in rightangled triangles, which form the basis of trigonometry. Spend time on this lecture to make abslutely sure you have Grade 10 and Grade 11 waxed.
Students  you must begin with a reveiw of Grade 10 adn Grade 11
Wolves  Get this right before proceeding to anayltical geometry.
Adults  You have to go back to the beginning a read the simple stuff the arithmetic rules dont apply here.
Parent  You have to cover this now. If you move on without getting it, your child is likely to run away from you through the tree. Stick with them.
Lions  Trig is one of the first areas you should finnish. It is important as it comes up later in Calculus and Fourier analysis andd then is all over Physics.
Instructors, Teachers, Manager  This is pattern recognition at the most extreme there are not a lot of questiosn before they strart repeating themselves.
