0.5=1-exp(-((x1+1)/0.9705)^0.8282
求x1,用什么计算?

0.5=1-exp(-((x1+1)/0.9705)^0.8282求x1,用什么计算?
先化简一下呗
0.5=1-exp(-(x1+1)/0.9705)^0.8282
exp(-(x1+1)/0.9705)^0.8282=0.5
0.8282(-(x1+1)/0.9705)=ln0.5
-(x1+1)/0.9705=(ln0.5)/0.8282
-(x1+1)=0.9705(ln0.5)/0.8282
x1=-0.9705(ln0.5)/0.8282-1
x1=0.9705(ln2)/0.8282-1
