Find the exact value of the following: \r
\n" ); document.write( "\n" ); document.write( "a) tan 65pi/6
\n" ); document.write( "65pi/6 = 60pi/6 + 5pi/6
\n" ); document.write( "10pi = 5*2pi
\n" ); document.write( "--> tan(5pi/6)
\n" ); document.write( "============
\n" ); document.write( "b) cos 150 (degrees)
\n" ); document.write( "Look up the unit circle.
\n" ); document.write( "------------------
\n" ); document.write( "c) sin 225 (degrees)
\n" ); document.write( "Look up the unit circle.
\n" ); document.write( "----------
\n" ); document.write( "d) sec 45pi/4
\n" ); document.write( "40pi/4 = 5*2pi
\n" ); document.write( "sec = 1/cos
\n" ); document.write( "Look up the unit circle.
\n" ); document.write( "
\n" ); document.write( "
