What is the difference between arcsin and co-secant?

Many threads I have read say they are equal but when I input them into a calculator I get different values.

arcsin is the inverse function of sine. It reverses what the sine function does.

cosec is the reciprocal of sine.

Generally, if you see , it will be referring to arcsin. Confusing, I know, but that is the notation unfortunately. The reciprocal of sine is almost always referred to as cosec. - April 27th 2010, 03:25 AMintegralQuote:

Even if not, how on earth would you notate the difference between arcsin and csc. ,

They look soo much the same. :(
