| 
 | 
 | 
- `s->qrot` => vector containing the indices of the rotational joints
 | 
| 
 | 
 | 
- `s->q_sin` => vector that contains the values of the joint sine (-2.0 if the joint is translational)
 | 
| 
 | 
 | 
- `s->q_cos` => vector that contains the values of the joint cosine (-2.0 if the joint is translational)
 |

- `s->flag_opti_symb_sin_cos` => a flag to activate the feature

- `s->flag_optim_symb_sin_cos` => a flag to activate the feature

## How to use
 | 
| 
 | 
 | 
The user should generate the symbolic files with the OptimSinCos(Rtime) option ON. Besides, the user must put `mbs_data->flag_opti_symb_sin_cos= 1;`just after the loading of the `.mbs` file in the main.c/.py
