SQL Tunning

Hello expert,
I have a table with 40 millions records and the last update date is indexed.
But when we use the
following where clause, it takes forever to run the report.
WHERE TRUNC(last_update_date) = TRUNC(SYSDATE - 1)
How to improve the performance? Do I need to create a new index field on the
table with TRUNC(last_update_date)?
