0 According to my HP-20S users manual: Changing the Trigonometric Mode "The trigonometric mode determines how numbers are interpreted when using the trigonometric and coordinate conversion functions." To set "Degrees Mode", press the yellow button to the left side of your calculator and then the DEG button (SIN button). There will be no annunciator notice. There are 360 degrees in a circle. To set "Radians Mode", press the yellow button to the left side of your calculator and then the RAD button (COS button). There will be an annunciator notice "RAD" displayed. There are 2Pi radians in a circle. To set "Grads Mode", press the yellow button to the left side of your calculator and then the GRD button (TAN button). There will be an annunciator notice "GRAD" displayed. There are 400 grads in a circle. To exit RAD or GRAD mode press, press the yellow button to the left side of your calculator and then the DEG button (SIN button). (Found on pages 34 and 35 of the manual. I hope this helps.
