To convert from degrees to radians, multiply by the conversion factor #(piquadcc( radians))/180^@#.
Here's the expression:
#color(white)=450^@#
#=450^@color(blue)(*(piquadcc( radians))/180^@)#
#=450^color(red)cancelcolor(blue)@color(blue)(*(piquadcc( radians))/180^color(red)cancelcolor(blue)@)#
#=450color(blue)(*(piquadcc( radians))/180)#
#=(450*piquadcc( radians))/180#
#=(color(red)cancelcolor(black)450^5*piquadcc( radians))/color(red)cancelcolor(black)180^2#
#=(5*piquadcc(radians))/2#
#=(5piquadcc(radians))/2#
Usually written as:
#=(5pi)/2quadcc(radians)#
That's the conversion. Hope this helped!
