Grade 11 Essential Unit G – Trigonometry

G-1 Unit G Trigonometry Class Notes. I have slightly elevated this unit beyond what the Grade 11 curriculum requires so that it actually covers a Grade 12 Unit thereby making Grade 12 a little less intense.

G-2 Grade 11 Essential Trigonometry Playlist – A selection of supporting videos. Investigate a couple that may help you explore a topic! You still need to do written work of course!

G-6 Prior Studies on Trigonometry. Since much of this Grade 11 Trig Unit (especially the latter half) is a repeat of prior Grades you might want to consult those resources.

Grade 8 Geometry; Grade 9 Geometry; Grade 9 Similar Triangles; Grade 10 Essential Trigonometry.

G-7 Sine Calculator Template. Estimate (pretty accurately!) your own Sine values graphically using this simple template. Can you figure out to make this calculate the Cosine also? Can you picture Sine and Cosine in your head now?
