V1162 is a delta-Scuti type variable star for which a rotational velocity of V sini=46 +/- 4 km s(-1) has been observed. The star has been modelled according to its observed parameters and oscillation frequencies. The results obtained by approximating rotation to the first order have been compared with the ones provided by new calculations that include rotation up to the second order. We found that second order rotation term should be included in frequency calculations for comparatively high rotation speeds.
