## LordVictorius 2 years ago What is the arcsin(1.16)?

1. geerky42

Are you allowed to use calculator?

2. LordVictorius

Yes.

3. LordVictorius

I don't have one.

4. LordVictorius

5. geerky42

Ok. it's undefined.

6. frogs29

go to mathway.com

7. LordVictorius

Okay, thanks.

8. geerky42

It doesn't exist.

9. LordVictorius

Okay, thanks.

10. LordVictorius

What is mathway?

11. frogs29

A math guide

12. LordVictorius

Okay, thanks.

13. frogs29

yup

14. mathsmind

what level are you at?

15. mathsmind

because i can give you the answer

16. LordVictorius

precalc.

17. mathsmind

1.570796327-.i5584022166

18. LordVictorius

lol, don't need that, but thanks.

19. mathsmind

20. mathsmind

well then it is undefined hehehe at ur level

21. mathsmind

everything has a solution but at ur level for the sake of simplification u say its undefined

22. LordVictorius

Okay.

23. LordVictorius

Geek, can you help?

24. LordVictorius

When I put in "arcsin(.9665 degrees) in degrees" into google, it gives me an identical answer.

25. LordVictorius

Why does it do that?

26. geerky42

Because a domain of $$sin^{-1}x$$ is [-1, 1] and .9665º is in between -1 to 1, so it is identified. Is this clear?

27. mathsmind

yes because u are in the R plane but if you migrate in complex world which is Z then the answer is different

28. LordVictorius

Yes, but what is the answer of arcsin(.9665 degrees)?

29. mathsmind

the R world sorry hehehe

30. LordVictorius

In the simple world please :P

31. geerky42

arcsin(.9665 degrees) = 0.0168694073

32. LordVictorius

33. geerky42

You can use WolframAlpha to calculate. http://www.wolframalpha.com/ Yeah, it is in radians. For degree, arcsin(.9665 degrees) = 75.12763776º $xº = \dfrac{180x}{\pi}$

34. LordVictorius

Okay, thanks.
