Bash does not support trigonometric functions and floating point operations at all.
Both bc and awk do, but personally I'd choose the latter, as it's easier to cut off the floating point part:
| Code: | # DEG=70; RADIUS=300; originX=0; originY=0
# SIN=`awk 'BEGIN {printf("%.0f\n", '$originX' + '$RADIUS' * sin('$DEG' * (3.14 / 180) ))}'`
# COS=`awk 'BEGIN {printf("%.0f\n", '$originY' + '$RADIUS' * cos('$DEG' * (3.14 / 180) ))}'`
# echo "Sin=$SIN Cos=$COS"
Sin=282 Cos=103
# |
Note that bc & awk operate in radians, that's why *(3.14/180).
PS.I was never good at trigonometry, but hopefully the above is correct...
Greetings!

Sorry.
I just entered man cos into the terminal and it just popped up this page in a browser. Just did not have deeper look into the results.
