Hello
i know how to derive the components of acceleration in other coordinates like spherical
start here :

and at last we have :

also , i know that acceleration is a contravariant vector :

but when i use that definition i don't derive the above result for acceleration !?
and reach to a different results
so what is my mistake ?
