Trigger 2
Detailed App Info:
Application Description
Trigger fosters a deeper understanding of trigonometry by building your geometric intuition.
The dynamic, touchable "Complete Triangle" figure interprets the six standard trig values associated with an angle as lengths of segments. As the angle changes, segments shrink to nothingness or stretch out to infinity, making the nature of individual values clear; segments also combine to form numerous similar right triangles, revealing many relationships among the values as simple geometric properties. Dual calculator displays allow for exploring these relationships numerically.
NEW IN VERSION 2.0:
▶ Completely re-designed.
▶ Now with Tau! Optionally view radian angle measures as fractions of a full turn, 1 tau ( = 2 pi ).
▶ Streamlined interaction: Change view settings and edit calculators without leaving the main screen.
▶ Universality: Trigger has an iPad-specific layout.
For information on the Complete Triangle figure, see the document "(Almost) Everything You Need to Remember about Trig, in One Simple Diagram", available at the Tricochet website.
