An excellent resource that shows alternative approaches to solving simple trig. ratio problems. Each problem is solved using
(i) the CAST diagram
(ii) a graphical approach
(iii) a quick method.
The PowerPoint begins with an explanation of how the CAST diagram works. These slides are aimed at the more inquisitive student and are not compulsory.
