How do you evaluate #csc 540#?

Answer 1

Asher Friedman

See below.

#csc (540)#

#= 1/ (sin (540))#

#= 1/ (sin (360 + 180))#

#= 1/(sin (180)) = oo#

To evaluate ( \csc(540^\circ) ), you can use the fact that ( \csc(\theta) ) is the reciprocal of ( \sin(\theta) ). First, find the sine of ( 540^\circ ), then take the reciprocal to find the cosecant value.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
