 * STUDENT PLANNER 2012 ** **__Topic: TRIGONOMETRY__** (Chapter 6) **NAME:**

Measurement in right angled triangles, the sine, cosine, and tangent ratios, angles of elevation and depression Both Pythagoras & **Trigonometry** play an important role in everyday life. They are integral to fields such as (not limited to) construction, navigation, planning, engineering, surveying, forestry, analysis of stock markets, design and packaging. |||||| ** VOCABULARY: ** trigonometry, hypotenuse, angle, opposite, adjacent, sine, cosine, tangent, theta ( θ ), Inverse, bearings, angle of elevation, angle of depression || eso – every second one LHS – left hand side RHS – right hand side CAS – graphics calculator || ** Classroom Activities ** || ** Consolidation Tasks ** || ** Enrichment & Extension Activities ** || ** Extra ** || Pg 283 Ex 6E Q1, Q2, Q4, Q5, Q6, Q7, Q8 || Worksheet 6E – 1 Labelling sides in right-angled triangles ||  || ** R ** eview today’s learning outcomes & complete any work not finished ||
