Trig Wizard I: Trigonometry for Visual Learners (ie. Most of us)
Trig Wizard provides an interactive, visual environment for teachers and learners for learning and investigating by interacting with a unit circle widget to:
⚫ Understand the fundamentals of trigonometry - Trig functions and their inverses, based on projection from/to unit circle
⚫ See the evolution of right-angled triangle trigonometry (SOH, CAH, TOA) from the unit circle
⚫ See trig identities as outcomes of unit circle symmetries
⚫ Solve trig equations visually
Plus numerous video tutorials:
For teachers
⚫ Easy use of interactive unit circle widget in class to demonstrate fundamentals of trigonometry to visual learners, which is most of them
⚫ An environment to visually demonstrate solutions to trig equations
⚫ For students – a self-paced learning environment for trigonometry
⚫ Introduction to widget, unit circle, sin, cos, tan projections, inverses
⚫ Development of right angled triangle trigonometry – SOH, CAH, TOA from unit circle
⚫ Animated worked examples for right-angled triangles and applications of trigonometry
⚫ 50 other categorized worked examples
Philosophy
Trig Wizard was designed and tested by teachers, for teachers and learners and was professionally developed, with:
⚫ Progressive in-class testing with multiple iPads
⚫ At-home testing by students as self-paced learning tool
Feedback from Teachers
“I will never again teach trigonometry without this tool”
“The visual environment allows any student to see relationships, minimizing the need to recall facts”
“The fact that students could either investigate the interactive widget or re-visit concepts via the video to go through at their own pace meant that all students could self-pace for any review”
Feedback from Students
“I found trigonometry so obvious that I cant believe my older brother had problems with it”
“I could always do trig and thought I understood it, but within a few minutes of playing with the app – I really did understand it”
“I did trig in school last year – didnt make much sense to me. Having gone through a few of the tutorials, it now seems so obvious. I have a mental picture of everything – so simple”
“The worked examples were very handy. I could always follow the same steps to identify trig ratios & do any other problem”
