Answer 1

within what range do you require'

Answer 2

I need it in radians between 0 and 2pi

Answer 3

first find what arcsin -1 gives you on your calculator
or r u familiar with the graph of sin x?

Answer 4

- that means 'the angle whose sine is '

Answer 6

oh ok hold on

Answer 7

my calculator said -1.57

Answer 8

ok to convert that to a positive angle add 2pi

Answer 9

-1.57 is same as - p/2

Answer 10

* -pi/2

Answer 11

2pi - pi/2 = ?

Answer 12
