The notes from todays lesson – covering Angles of Elevation and Depression. Slides (not annotated) Annotated Examples Remember the angle is always taken to the horizontal. An annoying YouTube video about this topic
For those needing a quick refresher on how to evaluate angles on the unit circle – for the HSC content simply substitute with radians and a slightly different version
Lesson 1 covered solving simultaneous equations by substitution – Lesson Notes – Solving by substitution Lesson 2 covered solving simultaneous equations by elimination – Lesson Notes – Solving by elimination
The first lesson covered radians – a measure of angle First Lesson Notes – Radians The second lesson covered – the special angles and radians. Second Lesson Notes
For those Year 11’s having trouble finding the Facebook group it is https://www.facebook.com/groups/khsacceleratedmathematics/
