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 range between 0 and 90 degrees into about 3 segments and
use a different approximation in each. And you need to pay attention to the
limited word length in order to get the best accuracy without overflow.
good luck
Roger

Hi! I'm working on a project where a robot needs to travel a right triangle with unkown side lengths. Basically, the robot starts at a point in a room, travels perpendicularly toward a wall, turns 90 degrees left when it hits, and when it gets to (...)
