I have a banked curve problem that I need to use. I was wondering if anyone knew the formula that includes friction. Thanks

We dont' give out formulas because that's not the way to solve a problem.

The only formulas you'll need are ones you probably know : for centripetal acceleration, frictional force, and Newton's 2nd Law.

Draw the free body diagram and solve Newton's 2nd along two perpendicular directions.
