For starters, try:

atemp = a*(2*pi)/360
btemp = b*(2*pi)/360
ctemp = c*(2*pi)/360

m = (cos(ctemp) * (cos(btemp) * x + sin(btemp) * (cos(atemp) * z +
  sin(atemp) * y)) - sin(ctemp) * ((cos(atemp) * y - sin(atemp) * z)))

n = (cos(ctemp) * ((cos(atemp) * y - sin(atemp) * z)) + sin(ctemp) *
  (cos(btemp) * x + sin(btemp) * (cos(atemp) * z + sin(atemp) * y)))

o = (cos(btemp) * (cos(atemp) * z + sin(atemp) * y) - sin (btemp) * x)
