c7b758f536 [poincare/expression] Fix solutions to e^x=0 
Because of the limitations of the floating-point representation, e^x is
null for x <= 710, causing the nextRoot functions to find roots for it.
To prevent this, we looking for places where a function changes sign, we
actually require the function to take two non-null values of different
signs.

1e7babadb8 [solver] Change angle unit before test 
A test in equation_solve relies on the angle unit being set to Degree,
but doesn't actually set it. Changing the angle unit to another one in a
test prior would break this test.

913c81a0d3 [solver] Modified the way to solve some equations 
The solutions of equations that need numerical approximations to be
solved are now computed base on the undeveloped equation (instead of
fully the expended one used to identify polynomials)

This allow (x-10)^7=0 to yield x=10 as result (9.95 before)

764cf1087a [apps/solver] Fix EquationStore::resolveLinearSystem 
Scenario: solve a system with the maximum number of variables -> our

k_maxNumberOfVariables, so we ended up adding the same children to the
matrix Ab, which created ghosts, which made the deep reduction crash.
