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))

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:
