弧長C=3.9米弧高H=0.6米半徑R多少?
Rn+1=(1-(Rn*COS(C/(2*Rn))-Rn+H)/((C/2)*SIN(C/(2*Rn))-H))*Rn
R0=3
R1=3.061
R2=3.063
R3=3.063
R=3.063米
弧長C=2.1米弧高H=0.6米半徑R多少?
Rn+1=(1-(Rn*COS(C/(2*Rn))-Rn+H)/((C/2)*SIN(C/(2*Rn))-H))*Rn
R0=0.9
R1=0.767
R2=0.791
R3=0.792
R4=0.792
R=0.792米
弧長C=3.3米弧高H=0.6米半R多少?
Rn+1=(1-(Rn*COS(C/(2*Rn))-Rn+H)/((C/2)*SIN(C/(2*Rn))-H))*Rn
R0=2
R1=2.14
R2=2.16
R3=2.161
R4=2.161
R=2.161米
