Year+10+11th+August+Lesson

=Computer Room Lesson on the 11th, 16th and 17th August 2011= Please note this can also be done at home. The files are stored in three places. They are on the student shared drive, available as applets in this wiki and as files (see number 2 below). If one option fails, try another! =1. Install Geogebra APPLET START from []= You may need the latest version of Java too. =2. From Geogebra Open the Geogebra files located in the student shared drive S:\maths\Ms Allan= =Also Here: = =3. Save them into your documents= =4. Look at the trig proof file= You may like to see the related video here http://2011mathsvideo.wikispaces.com/Trig+Ratios Applet is also stored @Applet Visual understanding SOHCAHTOA =5. Look at the pythag proof file= Applet is also stored @Applet Pythag =6. Look at the trig practise file and create your own questions as follows= - show 2 sides, find the 3rd side, repeat for every coloured side - show 2 sides, find one of the angles, repeat to find the other angle - show one side and one angle, find a side, repeat for the other side - show a different side or a different angle, in turn find all other angles and sides - keep going until you have used SOH CAH TOA and Pythagoras in every posible way Applet also stored @Applet Right Angle Triangles All =7. Record your use of the applet on the printed copy of this file= Systematically using the applet to ensure you have used Pythagoras and SOH-CAH-TOA every possible way. Student feedback was positive: Which makes this teacher happy to keep trying to get it right! "I found this really really really useful and it helped me so much because I find trig really hard. It makes it easy and with help from the teacher I did really well :-) I think I will use it at home because it will be helpful to study with. I still find trig hard but this helped me so much" "I found this task helpful and now I understand Pythag Cos and soh."

=8. Check out what Geogebra can do and have a play= http://geoart.wikispaces.com/ http://sltgeogebra.wikispaces.com/

=9. Extend your skills with this applet and check list= @Applet Advanced Pythag and Trig

=[] for the calculator emulator= =Hint: Use degrees not radians= Online calculators [] Then perhaps http://www.mathplayground.com/MathApprentice/Builders.html
