x= arccos(-√2/2) - cos(arcsin√5/3)

So I have f(x)= arccos(cos(x)). When I graphed it on a graphing calculator I see that the f(x) is ne...

what is the arccos(2)? I have tried to use the unit circle but I do not understand this :/.

what is the graph of y= arccos(x-2)

y=arccos(sin(x)), find dy/dx and sketch it's graph(I guess I can do this on wolframalpha after I'm d...

y=arccos(sin(x)), find dy/dx. I got -1, is this correct? When I tried to check on wolfram alpha I...

How do i get arcsin, arccos, arctan, arccot, arccsc, and arcsec on my calculator?

(arcsin(x/2)+arccos(x/2))/arctan(x) = 3/2, solve for x if x >0. Thanks.

1) What is the value of arccos x as x approaches 1 from the left? 2) What is the value of arcsin x...

Let \[f(x) = (\arccos x)^2 \cdot (\arcsin x)^2.\] Find the range of $f(x).$ All functions are in...
