What is the solution of cos(x) - sin(x) = 1
\n" ); document.write( "on the interval [0,360 degrees]
\n" ); document.write( "cosx-sinx= 1
\n" ); document.write( "square both sides
\n" ); document.write( "cos^2x-2sinxcosx+sin^2x=1
\n" ); document.write( "-sin(2x)+1=1
\n" ); document.write( "-sin(2x)=0
\n" ); document.write( "2x=0,180º
\n" ); document.write( "x=0, 90º \n" ); document.write( "

\n" );
