Use half-angle formulas to come up with an exact expression for each functionvalue below.I dont have to simily the answer.
\n" ); document.write( "tan(pi/6)
\n" ); document.write( "tan(pi/8).
\n" ); document.write( "==================
\n" ); document.write( "Using the formula tan(A/2) = (1-cos(A))/sin(A), we have
\n" ); document.write( "tan(pi/6) = (1-cos(pi/3))/sin(pi/3) = (1 - 0.5)/(sqrt(3)/2)) = 1/sqrt(3)
\n" ); document.write( "tan(pi/8) = (1-cos(pi/4))/sin(pi/4) = (1 - 1/sqrt(2))/(1/sqrt(2)) = sqrt(2) - 1 \n" ); document.write( "

\n" );
