RE: Equation with log LN
I still think there are 4 solutions. The calculator only calculates two. I made a similar equation x ^ 2-100 = LN (x). In this case, the calculator correctly solves the equation and gives 2 solutions. One solution x = 10.115 and x = 3.720E-44. It also solves unevenness well (see calculator screenshots).
Solution x = 3.720E-44 is a number almost equal to 0, but it is not zero. Similarly, in the equation x ^ 2-100 = LN (x), one solution is the number x> 1 and the other is the number x <-1. The calculator, however, does not calculate these values. He only gives x = -10.229 and x = 10.229.
But let this issue be decided by authority, the author of CAS.
