Question

I have a simple question, I just don't know what is going wrong with this!

sin(x)=8/144

Its acting weird when i try and calculate it.

Answer 1

what are you getting?

Answer 2

I'm trying to calculate this out, and it isn't working out right.

Answer 3

Something is just wrong with what i'm doing and I don't know where.

Answer 4

can you write what you have so far?

Answer 5

Its coming out as 0.0555... and I know that isn't right.

Answer 6

Absolutely.

Answer 7

ok so what you did was compute sin(8/144) to get 0.05552698

you are in radian mode btw

Answer 8

but you want to find the x value such that sin(x) = 8/144

Answer 9

so you have to use arcsine

Answer 10

sin^-1 right...?

Answer 11

correct

Answer 12

Okay now that I'm in degrees... its saying error.

Answer 13

how did you type it in?

Answer 14

8/144 then equals then sin^-1

Answer 15

what calculator are you using?

Answer 16

I've tried a scientific and my phone (which would be iphone)

Answer 17

ok I'm going to use wolfram alpha

Answer 18

I've tried Mathway too

Answer 20

I typed in "arcsin(8/144)" without quotes

Answer 21

Huh.
3.185 degrees.

Answer 22

that is saying the value of x is roughly 3.185 degrees, yeah

Answer 23

I wonder why I have been struggling with something so simple.

Answer 24

But thanks man

Answer 25

np

Answer 26

Huge help in my moment of confusion
