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 (...)
