BTW, trig/computer tidbit of the day: Alexa gets acos( ) and asin( )
For instance, she says that asin(0.5) is 0.0087, and that acos(0.5) is
1.5621. (Correct are 0.52 and 1.05.) Actually, it appears that all
asin( ) results are about zero, and all acos( ) results are about 1.57.
Also, for sin(x) and cos(x), x is in degrees, but for asin( ) and acos(
) the answer appears to be in radians.
I guess Alexa was distracted during her high school trig class.
I tentatively suspect that they did acos(degrees_to_radians(x)) instead
I filed a bug report.
