Activity

1. Open the word processor document called my equations. In this document, do the following:

Write a trigonometric equation:

   y = sin (30^o)

This procedure might help:

Open the equation editor
When the box opens, write y = sin
Then insert the round brackets ()
Inside the brackets write 30
Then choose ^o from the miscellaneous symbol menu:

Now try and write:

  y = ½ cos (A + B)

Click here if you need help with writing this equation.

Another common trigonometric equation looks like this cos2 = 2cos² -1. Try to type this equation using equation editor.

2. Now

EITHER

create a table that shows the sine, cosine and tangent values of the special angles 0^o, 30^o, 45^o, 60^o and 90^o

OR

Create a one page information handout with all the standard trigonometric identities.

3. Once you have created a teaching and learning resource using Equation Editor, share the document online with your group (using the subject heading "Equations resource").
   
   
4. Complete your e-diary about this activity.
