Question

Evaluate cos(sin^-1 0)

Answer 1

cos(sin^-1 0)

remember,
sin^-1 0=0,180,360

so,
=cos(sin^-1 0)
=cos(0) , cos180, cos360
=1,-1

Answer 2

so it's 1, -1?

Answer 3

what is arcsin in terms of sin or cos?

Answer 4

yes

Answer 5

arcsin(0) is only equal to 0
since -pi/2<=arcsin(x)<=pi/2

Answer 6

so cos(0)=1 like you said above
