The trigonometric functions atre in radians. How do I take the trigonometric
functins of angles in degrees?

For example, I have 30 in cell A2. In cell B2, I would like to take the
sine(30), where 30 is in degrees.

Thank you.

=sine(A2*PI()/180)

that should have been
=sin(A2*PI()/180)

For completeness, it might be noted that the RADIANS function
exists so that SIN(RADIANS(30)) = 0.5 etc. There is also a
corresponding DEGREES function that can be used to return an
inverse value in degrees, as for example, DEGREES(ASIN(0.5)) =
30.

Thank you very much, BJ.

Thank you, James. Your information will definitely come in handy when I am
working with the inverse trigonometric functions.
