Geogebra Interactive exercise that allows different triangles to be investigated with 1.05b step by step working. Malin Math Demonstration of area of triangle and the sine/cosine rules. 1.05b and Christersson’s Site 1.05c Geogebra Trigonometry area formula. 1.05c Shows how to find the area of a triangle including step by step working. Math Introduces the idea of radians in context. 1.05d Malin Christersson’s Site Includes a couple of questions at the end of the notes. Geogebra Interactive geogebra activity where learners must put the angles, given in 1.05d terms of , in the right place Underground Mathematics This resource provides an opportunity for students to practise calculating 1.05d arc lengths and sector areas. Students who look at the problem as a whole before jumping in with calculations will notice patterns and relationships between the sectors that provide more efficient routes through the task. Math Introduces the idea of combining known angle facts to determine others. 1.05f Malin Christersson’s Site Includes a couple of questions at the end of the notes. Chris Smith A very entertaining video that uses the circle and spaghetti to create a sine 1.05f curve. Geogebra Cosine Identity 1.05f link the corresponding values of on the graph Geogebra Sine Identity 1.05f link the corresponding values of on the trig graph Geogebra Tangent Identity 1.05f link the corresponding values of on the graph . Geogebra Gives the exact values of the trig functions around the circle. 1.05g
