Graph of an inverse trig function. Which of the following is equivalent to the graph of $arcsin(x)$ ?
(a) Reflecting $arccos(x)$ about the y-axis, then shift down by $\pi /2$ units.
(b) Reflecting $arccos(x)$ about the x-axis, then shift up by $\pi /2$ units.
I think they are both the same thing. Can someone confirm this ?

You can look at graphs of all three functions here:

Do they look the same to you?
