[4.3.1.0 port]  CAS: trig eqn: too many solutions
Answered
Let's start :wink:
(good morning)
Please have a look at this equation that:
 is not solved unless I expand it (well, I don't worry about this)
 has too many solutions (I mean, the CAS forgets that the equation has denominators, so solutions of the type x=k pi/2 are not acceptable)
Cheers,
S.

And here's another one.
Too many solutions  the equation has no solutions.
Again the denominator existence is not considered by CAS.
Take care,
S.

Solve[(1  cos(2x)) / sin(2x)  sin(x) / (1 + cos(2x))]
Solve[(cos(2x)²  sin(2x) sin(x) + 1) / (cos(2x) sin(2x) + sin(2x))]
Hi Mike,
sorry but your commands work exactly as the buttons, i.e. the first one gives ?, the second too many results :)
Cheers,
S.
