34 degrees is in the first quadrant of the central circle

34degrees=cos((17 pi)/90)

=0.83

Using a calculator-make sure it is set to deg. Look at the stop of the screen and it should say DEG and not RAD

input 34

Push "cos"

The other option is to use a standard trig chart

Find the cos for 30 degrees and 4 degrees and add them together to get the cos for 34 degrees.
