\n" ); document.write( "Find the exact value of tan 300 degrees. Use the sum or difference identity.
\n" ); document.write( "
\n" ); document.write( "Solution:
\n" ); document.write( "300 degrees = 5π/3
\n" ); document.write( "=2π-(pi/3)
\n" ); document.write( "
\n" ); document.write( "and we know that tan(2π)=tan(0)=0, and tan(π/3)=sqrt(3)
\n" ); document.write( "tan(300°)
\n" ); document.write( "=tan(2π-(pi/3))
\n" ); document.write( "=(tan(2π)-tan(π/3))/(1+tan(&2pi;)*tan(π/3))
\n" ); document.write( "=(0-sqrt(3))/(1+0)
\n" ); document.write( "=-sqrt(3)\r
