Question

how do i solve for sin^-1 (.018) I need to find the degree and radian

Answer 1

calculator

Answer 2

lol yeah but I still get 0.18... so is that the degree?

Answer 3

is your calc in degrees or radians?

Answer 4

.018001 is radians

Answer 5

that 0.018 is in radian
to convert it to degree
multiply by 180/pi

Answer 6

oh lol its on radians so i just switch it to degrees?

Answer 7

yes

or

degrees = radians * pi/180

Answer 8

Thanks :)

Answer 9

err degees = radians * 180/pi

Answer 10

so how many degrees u got?

Answer 11

1.03

Answer 12

Oh I thought you were him..

Answer 13

i was asking @Misaki-kun

Answer 14

i c

Answer 15

umm please hold

Answer 16

okay in degrees i got 10.36975980547742 or 10 i guess

Answer 17

nopes its 1.0317

Answer 18

thats not what I got

Answer 19

1.03 is what i got also.

Answer 20

\(0.018*180/\pi\)

Answer 21

what did you get zzr0ck3r

Answer 22

same as hartnn

Answer 23

okay let me try it again

Answer 24

i still got the same thing i got earlier you guys are doing .18 and not .018 right?

Answer 25

we ARE doing 0.018
because that the answer in radians.

Answer 26

OOOOOOOHHHH okay!

Answer 27

okay nevermind i still lost i think my calc is broken or i ain't typing it right but in radians I got 0.180986451246 so how you guys getting .018

Answer 28

our calcy gave us 0.018 and thats correct because for small angles in radians
sin x= x

Answer 29

correct, well aprx. hand wave and its all good

Answer 30

physics nerds love that one...:)

Answer 31

what calculator do you have?

Answer 32

the internet one

Answer 33

lol

Answer 34

use this one

Answer 35

okay

Answer 37

google agrees with us...

Answer 38

ha or google...that owns

Answer 39

by a ti89 or nspire, you will need it.

Answer 40

buy*

Answer 41

or steal one.

Answer 42

okay hey can you explain real quick though how sinx= x cuz i just can't feel good about my answer (even if it's right) if i don't understand how it works

Answer 43

do u know limits?

Answer 44

no

Answer 45

i can approximate the sin x curve for small angle with a line that has 45 degrees with horizontal,hence x and y co-ordinates are same.
so sin x = x for small angles.
