[FW Beta3] Solve APP failed... Can't understand...

[dg1969]

Hi,
Here is an example of a system equations...
degree mode is on...

Code:


E1: R+T-P*SIN(-15)=0
E2: S-Q+P*COS(15)=0
E3: -A*T+P*(D*SIN(-15)-C*COS(15))+B*Q=0

Unknowns are R, S and Q

So in fact the 1rst eq give R and then we have S and Q with E2 and E3

Code:


A:=2.62
B:=25.88
C:=0.97
D:=1.84
T:=450
P:=-1400

If I check only E2 and E3 The solutions for S and Q are OK:


But if I try to solve the three equations in a single system (E1, E2 and E3 are check) and with the num view complete like these:

The solve app change T and P !!! But T and P are not checked !! ? as you can see :

R solution is OK but S and Q are not !!!
The approx solutions are:
R=-88 ; S=1383 and Q=-31

Any help are welcome...
I do not understand what I'm doing wrong...
