U can't use the calculator directly.What's the definition of cosecant..?

No,it's inverse (one over) sinus.It's pretty delusive,but that's the definition.

cosecant= 1/sin
secant=1/cos
cot=1/tan

Algebra is the short answer.

1/(sin x)=a thus (sin x)=1/a

Use the value the problem gave directly. This will yield some angle (in radians). find the second angle using the proporties of sin i.e. where in the 4 quadrants is sin + and where is it negative.

Right below the blank "window" in which u write the text/body of the message u have the "Additional Options" menu where u'll find "Manage Attachments".Take a good look at the list of supported formats/extensions and keep in mind that anything over 50KB will not be uploaded;
