Algebra.Com's Answer #290663 by lwsshak3(11628)![]() ![]() ![]() You can put this solution on YOUR website! If sin A = sqrt 3/2, how do I measure angle A in radians? \r \n" ); document.write( "\n" ); document.write( ".\r \n" ); document.write( "\n" ); document.write( "There are many ways to do this. I will show you how I do it. \n" ); document.write( "First, The angle whose sin=sqrt(3/2)=60 deg \n" ); document.write( "Second, I remember that pi radians=180 deg. \n" ); document.write( "Then I take 60/180 as a fraction of pi radian. \n" ); document.write( "60/180*pi radians=(1/3)pi radians=pi/3 radians. \n" ); document.write( "so, 60 deg = pi/3 radians.\r \n" ); document.write( "\n" ); document.write( "..\r \n" ); document.write( "\n" ); document.write( "You can also use dimensional analysis. \n" ); document.write( "Just multiply pi radians/180 deg. by 60 deg. Degrees cancel and you end up with radians.If you were converting to degrees from radians,change the fraction to 180 deg/radians and multiply by radians to end up with degrees. Note that since 180 deg and pi radians are equal to each other, the fraction is equal to 1.\r \n" ); document.write( "\n" ); document.write( "Hope this helps. \n" ); document.write( " \n" ); document.write( " |
