Trig Help

[Wh005h]

Anyone mind getting me past this step? I need to determine what the value is of this portion of the equation.
tan[ cos^-1( 4 / 5 ) + sin^1( 1 ) ]
It would be greatly appreciated, but I can likely figure it out if no one helps within the day... I'm just tired of this one equation lol

It's either 11.623 or -21.452

I can't remember what you do first...

I'm pretty sure it's 11.623 though.
