$\"cos%28theta%29=4%2F5\"$
\n" ); document.write( " $\"sin%5E2%28theta%29%2Bcos%5E2%28theta%29=1\"$
\n" ); document.write( " $\"sin%5E2%28theta%29%2B16%2F25=25%2F25\"$
\n" ); document.write( " $\"sin%5E2%28theta%29=9%2F25\"$
\n" ); document.write( " $\"sin%28theta%29=0+%2B-+3%2F5\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"cot%28theta%29=cos%28theta%29%2Fsin%28theta%29=%284%2F5%29%2F%280+%2B-+3%2F5%29=0+%2B-+4%2F3\"$
