  • Y1 = 2Y4/Y7+Y3e-0.2iPart(5sin(x2)+3sin(x(Y2≥Y8)))
  • Y2 = Y7(0.5x3-x2-2x+normalpdf(x,x,x)+0.8)
  • Y3 = (angle(x)+10.76/Y7+11.09e-0.547x)-8.1
  • Y4 = (cos(x(fPart(Y3-√(Y3 OR x≠Y8)+2)≤5)))2+0.11
  • Y5 = (Y1<Y8)+(Y1≥0.9)+2
  • Y6 = Y1+Y7+Y8-Y5+x√(x)
  • Y7 = e10-x-1-e-0.0015
  • Y8 = π(tcdf(0,25,x)-0.5)
  • Y9 = (-poissoncdf(x,x)+1.61)Y62pdf(x,1)+Y8
