Slope Tangent Ratio Teaching Help Math Fun Trigonometry Angles Coordinates Graphing Game

Teaching Slope = Tangent Ratio        Trigonometry Fun Math Help        Game Tips:

- Press the 't' key to see a graph that demonstrates the following example.
- The tangent of angle A can be written as tan A and equals the slope from point A(0,0) to point D(2,4).
    This tangent ratio = slope = (rise)/(run) = (change in y)/(change in x) = (4-0)/(2-0) = (4)/(2) = 2/1.
- Press the 'y' key to restart the game.

- Generally, when angle A is in standard position as shown at this graph's origin (0,0)
    then tan A equals the ratio = (rise)/(run) = slope.
