How is 1/sin250=2.37

signal sealBOT May 7, 2023, 4:05 PM

#

placid crystal May 7, 2023, 4:06 PM

#

when I do it I get -1

reef spindle May 7, 2023, 4:08 PM

#

placid crystal when I do it I get -1

are you in deg or rad

#

also, for which one do you get -1

placid crystal May 7, 2023, 4:11 PM

#

i think deg

reef spindle May 7, 2023, 4:11 PM

#

Can you check

#

I have the same answer as them

placid crystal May 7, 2023, 4:11 PM

#

how do I do that

reef spindle May 7, 2023, 4:11 PM

#

what are you using

#

TI?

placid crystal May 7, 2023, 4:11 PM

#

on my calculator

#

casio

#

fx300ms

#

#

this calculator

reef spindle May 7, 2023, 4:12 PM

#

what does "MODE" do

placid crystal May 7, 2023, 4:12 PM

#

Comp SD REG
1 2 3

reef spindle May 7, 2023, 4:12 PM

#

placid crystal when I do it I get -1

it's actually weird. Even if I'm in radians, I get -7.55. That's nothing close to -1

#

And in deg, it's the same as the picture

placid crystal May 7, 2023, 4:13 PM

#

and then if I press on mode again

#

I get

DEg Rad gra
1 2 3

#

and then I Press 1 on the numpad

reef spindle May 7, 2023, 4:14 PM

#

It's not the same model, but I'm sure the steps are similar

How to Convert Between Degrees and Radians on Casio Scientific Calc...

This is a video in my Scientific Calculator Tutorial series. The calculator I use in the video is a Casio Fx-300 MS. However, this should be applicable to similar model calculators. In this video, I go over how to convert from degrees to radians and from radians to degrees. I also discuss how you can do operations in radians while in degree mo...

Same model

#

Ok

#

Press mode twice

placid crystal May 7, 2023, 4:19 PM

#

done

#

placid crystal sorry internet went out

damn

#

that's tough

placid crystal May 7, 2023, 4:20 PM

#

@reef spindle what mode should i be in

#

degree right?

reef spindle May 7, 2023, 4:20 PM

#

yuh

#

#

Remember small details

#

they tell you that it should be in deg

placid crystal May 7, 2023, 4:23 PM

#

yea

#

im doinog

#

1/sin(250)

#

and im getting

#

-1

reef spindle May 7, 2023, 4:24 PM

#

mate

#

that's sin25

sage phoenix May 7, 2023, 4:24 PM

#

No

reef spindle May 7, 2023, 4:24 PM

#

not 250

sage phoenix May 7, 2023, 4:24 PM

#

25°

reef spindle May 7, 2023, 4:24 PM

#

Yeah ^

placid crystal May 7, 2023, 4:24 PM

#

oh

#

shit

#

im

reef spindle May 7, 2023, 4:24 PM

#

😭

placid crystal May 7, 2023, 4:24 PM

#

ok im getting 2 now

sage phoenix May 7, 2023, 4:25 PM

#

I will say in the 1/sin25° one it REALLY looks like 1/sin250

reef spindle May 7, 2023, 4:25 PM

#

thank god

placid crystal May 7, 2023, 4:25 PM

#

she got 2.37 let me try tan52

reef spindle May 7, 2023, 4:25 PM

#

sage phoenix I will say in the 1/sin25° one it REALLY looks like 1/sin250

The previous one denoted deg tho

#

Idk man

#

Hard pass

placid crystal May 7, 2023, 4:26 PM

#

im getting 1

reef spindle May 7, 2023, 4:26 PM

#

Are you serious

placid crystal May 7, 2023, 4:26 PM

#

for 1/(tan52)

reef spindle May 7, 2023, 4:26 PM

#

wait let me check

#

it should be 0.781

placid crystal May 7, 2023, 4:28 PM

#

1 sec

#

when I put sin in my calculator

#

its not Sin^-1

#

just sin

reef spindle May 7, 2023, 4:30 PM

#

you don't need arcsin

placid crystal May 7, 2023, 4:30 PM

#

oh

#

i have to press sin

#

and then shift

reef spindle May 7, 2023, 4:30 PM

#

yeah

#

not arcsin

placid crystal May 7, 2023, 4:30 PM

#

ok got same answer

#

as her

#

let me try

#

tan 1

reef spindle May 7, 2023, 4:31 PM

#

send me a picture

#

how is this even possible wtf

placid crystal May 7, 2023, 4:32 PM

#

i tried this

#

and got 38 degrees

#

sin^-1(.62)

reef spindle May 7, 2023, 4:32 PM

#

wait

#

what are we doing now

placid crystal May 7, 2023, 4:32 PM

#

reef spindle May 7, 2023, 4:32 PM

#

I thought it was 1/sin(25)

placid crystal May 7, 2023, 4:32 PM

#

lets do this

#

lol

#

oh i did that and got the answer

#

let me just do it again

#

to double check

reef spindle May 7, 2023, 4:32 PM

#

placid crystal

why are you using arcsin

placid crystal May 7, 2023, 4:32 PM

#

lmao

reef spindle May 7, 2023, 4:32 PM

#

what

#

what

#

wait no

placid crystal May 7, 2023, 4:33 PM

#

not for that 1

#

1 sec

#

1

#

sec

#

lets just do

#

#

this now

reef spindle May 7, 2023, 4:33 PM

#

oh ok

#

lol

placid crystal May 7, 2023, 4:33 PM

#

lets see

reef spindle May 7, 2023, 4:33 PM

#

sure

placid crystal May 7, 2023, 4:33 PM

#

1/tan52

#

in my calculator it should be

reef spindle May 7, 2023, 4:33 PM

#

yes

placid crystal May 7, 2023, 4:33 PM

#

1/tan (52)

#

right

reef spindle May 7, 2023, 4:33 PM

#

yes

#

make sure its in deg

placid crystal May 7, 2023, 4:34 PM

#

I got 1

#

let me watch the calc vid again

reef spindle May 7, 2023, 4:34 PM

#

can you...

#

send a pic of that

#

like you writing 1/tan(52) and it says 1

placid crystal May 7, 2023, 4:35 PM

#

ok im just stupid

#

i think i figured it out

#

1 sec

reef spindle May 7, 2023, 4:36 PM

#

Are you in precalc

placid crystal May 7, 2023, 4:36 PM

#

im sending a pic

#

shits aids

#

1 sec

#

reef spindle May 7, 2023, 4:38 PM

#

....

#

wha the actual florida

#

what about this

#

evalutate tan(52)

#

and then divide 1 by that number

#

so just tan(52)

#

whatever number comes out, 1/number

placid crystal May 7, 2023, 4:39 PM

#

tan (52degrees)

#

=1

#

lol

reef spindle May 7, 2023, 4:40 PM

#

???????

placid crystal May 7, 2023, 4:40 PM

#

ye

#

idk

reef spindle May 7, 2023, 4:40 PM

#

it's 1.28

#

I don't know what to say

#

Can you ask your teacher or something next class

#

It's just that your tan function isn't working, I have no idea how 💀

placid crystal May 7, 2023, 4:41 PM

#

yeea

#

im gonna try another calculator later

#

#

im doing this

#

1/sin250

#

and getting 2

#

i do 1/tan52

reef spindle May 7, 2023, 4:42 PM

#

bro

placid crystal May 7, 2023, 4:42 PM

#

i get 1

reef spindle May 7, 2023, 4:42 PM

#

bor

placid crystal May 7, 2023, 4:42 PM

#

loll

reef spindle May 7, 2023, 4:42 PM

#

bro

#

it's 1/sin25

placid crystal May 7, 2023, 4:42 PM

#

i meant

#

1/sin25

#

lol

reef spindle May 7, 2023, 4:42 PM

#

oh ok

#

so that's ALSO wrong?

#

are you in the "gradient" mode or whatever that was

placid crystal May 7, 2023, 4:43 PM

#

yes

#

no

#

degree mode

#

should I try

#

rad mode

reef spindle May 7, 2023, 4:43 PM

#

it won't match the vid tho

#

Abandon casio, obey TI-84

placid crystal May 7, 2023, 4:44 PM

#

yea

reef spindle May 7, 2023, 4:44 PM

#

idk man it's weird tho

placid crystal May 7, 2023, 4:48 PM

#

ok

#

@reef spindle

#

I got it to work

#

got the right answers

#

cant use the brackets with tan and stuff

#

its what ruins it

#

nvm works with brackets

#

guess i was in the wrong mode

#

lol

reef spindle May 7, 2023, 4:49 PM

#

jeez

#

so you got it ?

#

my calc uses brackets

placid crystal May 7, 2023, 4:49 PM

#

yea

#

i got it

#

now its time to start learning.. 5 lessons
