Algebra.Com's Answer #22070 by venugopalramana(3286) You can put this solution on YOUR website! Hi. I need help with the following problem. \"Find the solutions of the equation in interval [0,2pi).\" the problem is \n" ); document.write( " secx+tanx=1...............................I \n" ); document.write( "WE KNOW THAT SEC^2(X)-TAN^2(X)=1={SEC(X)+TAN(X)}{SEC(X)-TAN(X)} \n" ); document.write( "HENCE FROM EQN.I ,WE GET THAT \n" ); document.write( "SEC(X)-TAN(X)=1................................II \n" ); document.write( "EQN.I+EQN.II....GIVES \n" ); document.write( "2SEC(X)=2 \n" ); document.write( "SEC(X)=1 \n" ); document.write( "COS(X)=1 \n" ); document.write( "X=0......ONLY AS THE NEXT SOLUTION 2PI IS EXCLUDED FROM THE RANGE\r \n" ); document.write( "\n" ); document.write( "The only thing I did was subtract the one, but now i'm unsure what to do.
