L1 LbI
L3 S=R-O:C=Abs((F-D)RO/S)
L4 R>O=> P=CR/((E-F)NR+C):≠> P=CR/((F-E)NR+C)△
L5 I=PR/(P+R)
L6 U=V-180(E-F)/2/I/π
L7 R<O=> M=Abs(F-D)+C/O: ≠> M=C/R△
L8 R<O=> Q=F-NM: ≠>Q=F+NM△
L9 L=Abs(E-Q)
L10 A=(L-M)-(Lxy5-M xy5)/40/C2+(Lxy9-Mxy9)/3456/ Cxy4:B=( Lxy3-Mxy3)/6/C-(Lxy7 -Mxy7)/336/ Cxy3+( Lxy11-Mxy11)/42240/ Cxy
L12 T=V-180NPM2/2/π/C
L13 X=G+PA cos T-NB sin T:Y=H+PA sin T+NB cos T
L14 X=X+W cos(U+K)▲Y=Y+W sin(U+K)▲
