Lame questions in which i have no idea how to do (1 Viewer)

State the domain and range of

y= inverse sin (x^2)
y= x inverse cos x
y= inverse sin (tanx)

Here are some hints:

a) y = arcsin(x²)

=> x² = sin(y)

b) y = xarccos(x)

=> x = cos(y/x)

c) y = arcsin(tan(x))

=> tan(x) = sin(y)


go from there

first of all.. wtf is a "arc" i have never come across this.

arctanx=inverse tanx=tan^-1x
arcsinx=inverse sinx=sin^-1x
arccosx=inverse cosx=cos^-1x

Another way of saying inverse (something)

I believe this is the conventional way that American mathematicians call it.
