Information About The Program
Trig Stuff (Tool)
This program gives students a visual representation of sine and cosine at different angles. A unit vector will cycle through different angles and students can see the changes that take place to the horizontal part and the vertical part of the vector. They will be introduced to sine as the percent of the hypotenuse for the opposite leg of the triangle and cosine as the percent of the hypotenuse for the adjacent leg. They will see that the percentages add to 100 percent when added in a pythagorean sense.
