Question

How do you find csc(134°25'33")?

Answer 1

`csc x=1/sinx`

Explanation:

If your calculator does not support minutes and seconds notation, you first calculate `134+25/60+33/3600`

Then take the sinus of this: `sin ANS`

Then take the inverse of that last answer: `1divANS`

Or you can do it all in one go (don't forget the brackets):

`1div(sin(134+25/60+33/3600))`

Answer 2

Use conversion that there are 60 arc-minutes in a degree and 3600 arc-seconds in a degree to convert to decimal degrees.
Take sine of the resulting angle
Take the reciprocal of the sine.

Explanation:

Make sure that you calculator is in "degree" mode for the trigonometric functions.

Convert `134^@ 25" arc-minutes "33" arc-seconds"` to an decimal number by entering the following:

`( 134 + 25 -: 60 + 33-:3600)`

You calculator should be displaying:

134.42583333333333333333333333333

Hit the key for the sine function and your display should be:

0.6152087839822711170293545842147

Hit the 1/x key and your calculator display should be:

1.6254644374986974646079832099469
