Question

So I need a bit of help. I am a bit confuzzled...

Answer 1

Can you insert like \(\sec, \csc , \cot\) on a calculator?

Answer 3

Like in a type of calculator? Especially in a Scientific calculator.

Answer 4

just put 1/sin, 1/cos,1/tan if you don't have those button

Answer 5

I have seen a button for \[\sin, \tan, \cos\] and \[\sin^{-1}, \cos^{-1}, \tan^{-1}\]

Answer 6

@experimentX yeah that is what I thought, but i was wondering if there was a calculator out there that had a function for those specific trig functions.

Answer 7

another way is , like you want find csc30
we knowed that csc = 1/sin
so, first push 30 then sin, get the result, and then push 1/x (it means the reciprocal of sin30)

Answer 8

you will get it is 2

Answer 9

so what would be x?

Answer 10

what sin30 is right?

Answer 11

have you tried this before :)

Answer 12

\[\sin (30) = \frac{ 1 }{ 2 }\]

then:

\[\frac{ 1 }{ x } = \frac{ 1 }{ \frac{ 1 }{ 2 } } = 2\]

Answer 13

Even the Ti-36x Pro, which has an insane number of buttons, does not do those directly. Let me look at the TRi-nSpire. Do not see them there either and that thing has tons of extra functions I rarely use.

I think calculators rely on you knowung how to use the \(\frac{1}{\square}\) key to get these.

Answer 14

@e.mccormick you have a TRi-nSpire?

Answer 15

THANK YOU ALL :)

Answer 16

No R. Just Ti... poor typing skills. =P

Answer 17

similarly to calculate arccsc(x) ... just calculate arcsin(1/x)
