Question

In what mode should I calculate CSC(co secant) in my calculator?

Answer 1

In many calculus classes, I've seen radians being the default mode. In this special case, it doesn't matter because 0 radians = 0 degrees, so they're both approaching 0.

Answer 2

Also, keep in mind that

\[\Large \csc(x) = \frac{1}{\sin(x)}\]

Answer 3

SO sinx equaling zero is just a rule im going to have to memorize right?
In that case shouldnt 0/0 pose a problem? since the denominator is sinx
The answer was infinity by the way

Answer 4

wait sorry brain fart ignore last message

Answer 5

If you input 1/sin(0) into your calculator, you'll get an error message, which means that the limit doesn't exist. In other words, infinity.
