Thank you for these posts! This idea of creating a table of arctangents is just what I need. I'll let everyone know how it works after I redesign the racer.

Wouldn't it be cool if someone built a robot (Lego or otherwise) that could play Jenga. It would need sensetive devices to determine the force required to withdraw a block. It would then have to build up a model of the tower in memory to enable it (...) (24 years ago, 14-Dec-01, to lugnet.robotics)

Hi Richard, No, NQC does not implement any of the trig functions. However, you can do it yourself. The idea is to use a second order polynomial to approximate the sine function. You can get pretty good accuracy (within about 5%) if you break up the (...) (24 years ago, 12-Dec-01, to lugnet.robotics.rcx.nqc)
