已知弦长3.36和弧长3.5,求半径 已知弦长0.83和弧长0.95,求半径
答
已知弦长L=3.36和弧长C=3.5,求半径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
已知弦长L=0.83和弧长C=0.95,求半径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弦长2.54 弧长2.56 求半径，谢弦长L=2.54 弧长C=2.56 求半径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
