You can put this solution on YOUR website!
Ah! Finally one can be done without calculator...(Just found mine missing)
\n" ); document.write( "cot(π)=cos(π)/sin(π)=-1/0=undefined
\n" ); document.write( "(according to definition of cos and sin using unit circle) \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "But we can see the limit as x approaches π of cot(x) is -1/0, which is equivalent to approaching positive infinity.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In fact we don't literally need a calculator... it would just return a silly \"Math Error\". Hah!
