    WHY can't your calculator do cos4(10)? It certainly looks straightforward. Do you get some kind of error message?

    Well from your post it's pretty clear that you don't even understand what cos^4(10) means, so surely the underlying problem is here and not with the calculator.

    [itex]\cos^n(x)[/itex] means [itex](\cos\,x)^n[/itex], ok.

    So now you know what it means I suppose that your calculator will now be able to do it.
