Work: Find the solution of equation (e(x*0.161937-12.955)/(1+(e(x*0.161937-12.955)) ) ) = 1 .
Question type: Equation
Solution:
After the equation is converted into a general formula, it is converted into:
( 1000000x - 307082387 )( 1000000x - 307827901 )( 275x - 84859 )( 100000x - 30931893 )( 250000x - 77795679 )( 250000x - 77795679 )( 1000000x - 311555473 )( 100000x - 31192823 )( 250000x - 78075247 )( 200000x - 62534749 )=0
From
1000000x - 307082387 = 0
1000000x - 307827901 = 0
275x - 84859 = 0
100000x - 30931893 = 0
250000x - 77795679 = 0
250000x - 77795679 = 0
1000000x - 311555473 = 0
100000x - 31192823 = 0
250000x - 78075247 = 0
200000x - 62534749 = 0
it is concluded that:：
| x1= | 307082387 1000000 |
| x2= | 307827901 1000000 |
| x3= | 84859 275 |
| x4= | 30931893 100000 |
| x5= | 77795679 250000 |
| x6= | 77795679 250000 |
| x7= | 311555473 1000000 |
| x8= | 31192823 100000 |
| x9= | 78075247 250000 |
| x10= | 62534749 200000 |
