I am trying to solve a system of equations:

```
using SymPy
@syms F_t delta F_a beta_c F_tp F_ap g_p theta v lambda
g = 9.81
m = 9.2;
r = 30;
eq1 = F_t*cos(delta) - F_a*cos(theta) + m*g*sin(beta_c)
eq2 = (m*v^2)/r - F_t*sin(delta) - m*g*cos(beta_c)*cos(lambda) - F_a*sin(theta)
solve([eq1, eq2], [F_t, theta])
```

I know that a solution exists (other CAS systems can find them), even though the result is quite complex.

But solve just hangs, no error message, no result.

Any idea?
