Solution:We know that: $\"%28sin%28theta%29%29%5E2%2B%28cos%28theta%29%29%5E2=1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28cos%28theta%29%29%5E2=1-%28sin%28theta%29%29%5E2=1-%281%2F3%29%5E2=1-%281%2F9%29=8%2F9\"$ and\r
\n" ); document.write( "\n" ); document.write( " $\"cos%28theta%29=sqrt%288%2F9%29=%282sqrt%282%29%29%2F3\"$ \r
\n" ); document.write( "\n" ); document.write( "tan(theta) =sin(theta)/cos(theta)=(1/3)/(2sqrt(2)/3)=1/(2sqrt(2)\r
\n" ); document.write( "\n" ); document.write( "Done. \n" ); document.write( "
