    Question Question about converting sine in degrees to radians

    Is the formula to convert degrees to radians (number * pi/180) the same for all shapes; for example if I wanted to find the sine of an octagon would I do number* pi/1080?

    Please help. Thanks.

    Re: Question about converting sine in degrees to radians

    Radians and degrees are simply two different units of measurement for an angle, like for example metres and feet are two different units of length or gallons and litres are two different units of volume.

    2\pi radians gives you the same angle as 360 degrees, a complete circle.

    1 radian gives you the same angle as 360/(2\pi) \approx 57.296 degrees.

    1 degree gives you the same angle as 2\pi/360 \approx 0.01745 radians.

    The relationship is independent of sines, cosines or octagons.
