How do you use a calculator to evaluate #cos^-1 (0.55)# in both radians and degree?
Caroline AdamsOn most trig function calculators, 2nd > cos (this should give you cos^-1) and input your values.
To change the mode of your calculator, hit mode and you should be able to scroll down to change to and from degrees and radians.

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.
