Greetings all! I just got the Sharp GP2D02 ir distance sensor and I got it all hooked up the way that Barry Brouillette's tutorial explained, and I downloaded the new expansion board drivers, but when I went to load the Barry's IR drivers, it gave (...)

(...) This is actually a very good question. Generally, math function libraries use what is called a Taylor series expansion of a trigonometric function to return an approximation to the function with arbitrary precision. The more terms from the (...) (25 years ago, 5-May-99, to lugnet.robotics.handyboard)

(...) Dear Andrew, You want the angle that line joining G and P make with X axis. That is arctan of the slope of the line from P to G. slope =(yP-yG)/(xP-xG) hence, theta = arctan ((yP-yG)/(xP-xG)) where P=(xP,yP) and G=(xG,yG) Note that this angle (...)
