True or False

1) show a diagram to explain sin(5) > sin(2) in term of radians

2)sin^-1(x) = 1/sin(x) ( True or false?) if true explain why this holds for all value of x. If not true, give a value for x that shows it is not true

3) the domain for cos^-1(x) is [-1,1] because this defines the values for x so that cos(x) > 0

if true, explain. if false, change the statement above to make it true
