Finding Exact Trig Values WORKSHEET DESCRIPTION
This worksheet leads learners through finding the exact trigonometric ratios for 0, 30, 45, 60 and 90 degrees.
Section A introduces the concept of the unit circle and asks learners to estimate values from reading from the graph.
Section B then introduces the first of the special triangles that can help learners derive some of the values.
Sections C and D use the triangles and ask for tables of the ratios to be completed.
Section E then asks for all of the values to be summarised in a new table.
All worksheets are created by the team of experienced teachers at Cazoom Maths.
