Aimed at SL IB but easily applicable to KS3 & 4 groups.

Presentation is focused on 2 aspects, taking a trig result and using that to show what the other ratios would be (without a calculator). Secondly it looks at elevations and depressions.

problems include having to recall without a calculator the values of common angles.

questions and discussion points built into the presentation

answers are included
