$\"sin%5E2%28theta%29%2Bcos%5E2%28theta%29=1\"$
\n" ); document.write( " $\"%28-3%2F5%29%5E2%2Bcos%5E2%28theta%29=1\"$
\n" ); document.write( " $\"9%2F25%2Bcos%5E2%28theta%29=1\"$ }
\n" ); document.write( " $\"cos%5E2%28theta%29=25%2F25-9%2F25\"$
\n" ); document.write( " $\"cos%5E2%28theta%29=16%2F25\"$
\n" ); document.write( " $\"cos%28theta%29=0+%2B-+4%2F5\"$
\n" ); document.write( "Since $\"pi+%3C+theta+%3C+%283%2F2%29pi\"$ ,
\n" ); document.write( " $\"cos%28theta%29=-4%2F5\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"tan%28theta%29=sin%28theta%29%2Fcos%28theta%29\"$
\n" ); document.write( " $\"tan%28theta%29=%28-3%2F5%29%2F%28-4%2F5%29\"$
\n" ); document.write( " $\"highlight_green%28tan%28theta%29=3%2F4%29\"$ \r
