An activity to discover the properties of the graphs of sine and cosine. Print off the circle and horizontal axis for each student. Enlarge to A3 if you want to make a display afterwards. You just need to provide some spaghetti and glue.

This is great for teaching trigonometry for angles greater than 90 and visualising the shape of the sine and cosine curves. My students particularly enjoy this one and hope yours do to.

Two worksheets for the price of one. Both worksheets have identical questions but one is in degrees and the other is in radians.

Great practice for solving simple trigonometric equations but also practising the using identities (tanx=sinx/cosx and sin^2(x) + cos^2(x)=1) and equations such as sin2x = a or tan3x = b

Both worksheets include worked solutions to aid self/peer assessment.

Treasure/Scavenger Hunt - Using trigonometry to find missing lengths

Worksheet that contains a mixture of the law of sines and law of cosines. Also includes problems on finding the area of triangles using 1/2 absinC.

Questions increase in difficulty to include problems where both rules are needed or one rule is needed before being able to find the area of the triangle.

This works well after teaching sine and cosine rule separately and students need to be able to decide when to use each rule.

Worked solutions are included
