Description

In the tree below, the exponentiation factor becomes very large (about e30 ) while the other factor (5,5606E-016) shrinks this output down into a valid range. However, in the simplifier, this is reduced to a constant, because (5,5606E-016) is too small. The values of Variable X1 are in the range of 0,2 and 1.0
