Use the first five terms of the trigonometric series (shown below) to approximate sin(π/5).\r
\n" ); document.write( "\n" ); document.write( "sin(x)=x-x^3/3!+x^5/5!-x^7/7!+...
\n" ); document.write( "-------------
\n" ); document.write( "You listed 4 terms.
\n" ); document.write( "sin(x)=x-x^3/3!+x^5/5!-x^7/7!+x^9/9!
\n" ); document.write( "--> 0.59456922
\n" ); document.write( "--> 36.48 degs or 0.202674889*pi radians
\n" ); document.write( "
\n" );
