Ricky Pedersen Cooking up maths ideas since 2005
Linking the unit circle with Trigonometric functions 3 types of functions looked at in year 11 Sine Cosine Tangent How many of us show students that sin cos and tan are more than just buttons on a calculator?
So….. Where does the pasta come in?!?!
Materials required Couple of packets of budget spaghetti A3 or A4 Paper Glue or Sellotape A little time to prepare A small class of students (yeah right!)
Sine – uses the y components (opposite) Cosine – uses the x components (adjacent) θ Hypotenuse (radius)
Going off on a tangent…. Extend your students by looking at the tangent function Don’t use the pasta as an asymptote ;)
