已知弦長L=3.36和弧長C=3.5,求半徑R?
Rn+1=(1+(L-2*Rn*SIN(C/(2*Rn)))/(L-C*COS(C/(2*Rn))))*Rn
R0=3
R1=3.377
R2=3.351
R3=3.351
R=3.351
已知弦長L=0.83和弧長C=0.95,求半徑R?
Rn+1=(1+(L-2*Rn*SIN(C/(2*Rn)))/(L-C*COS(C/(2*Rn))))*Rn
R0=0.5
R1=0.53
R2=0.535
R3=0.535
R=0.535弦長2.54 弧長2.56 求半徑，謝弦長L=2.54 弧長C=2.56 求半徑R?Rn+1=(1+(L-2*Rn*SIN(C/(2*Rn)))/(L-C*COS(C/(2*Rn))))*RnR0=6R1=5.901R2=5.905R3=5.905R=5.905
