$\"cos%28theta%2F2%29%7D%7D+=+0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"theta%2F2\"$ $\"%22%22=%22%22\"$ $\"pi%2F2\"$ or $\"3pi%2F2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"theta\"$ $\"%22%22=%22%22\"$ $\"2pi%2F2\"$ or $\"6pi%2F2\"$ }\r
\n" ); document.write( "\n" ); document.write( " $\"theta\"$ $\"%22%22=%22%22\"$ $\"pi\"$ or $\"cross%283pi%29\"$ \r
\n" ); document.write( "\n" ); document.write( "We can't use $\"3pi\"$ because it's not in the interval $\"%28matrix%281%2C3%2C0%2C%22%2C%22%2C2pi%29%29\"$ \r
