\"sin%283pi%2F2%29=-1+\" in radians-> Conversion from radians to degrees, it's equal to: sin(\"270+\"°) ->sin(\"270=-1+\"°) (III quadrant)\r
\n" ); document.write( "\n" ); document.write( "use Unit Circle and you will see that \"270=3pi%2F2\" and sine of both is \"-1\"\r
\n" ); document.write( "\n" ); document.write( "\"cot+%283pi%2F2%29=0\" or \"cot%28270%29=0\" \r
\n" ); document.write( "\n" ); document.write( "use Unit Circle and you will see that \"270=3pi%2F2\" and cos of both is \"0\"\r
\n" ); document.write( "\n" ); document.write( "since \"cot%28x%29=cos%28x%29%2Fsin%28x%29\"=>\"cot%28x%29=0%2F1=0\"
\n" ); document.write( "
\n" );
