Algebra.Com's Answer #484196 by Alan3354(69443) You can put this solution on YOUR website! Find all solutions of the equation in the interval [0,2pi) \n" ); document.write( "cosx(cotx-sqrt3)=0 \n" ); document.write( "------------ \n" ); document.write( "cos(x) = 0 --> x = pi/2, 3pi/2 \n" ); document.write( "--- \n" ); document.write( "cot(x) = sqrt(3) \n" ); document.write( "tan(x) = sqrt(3)/3 \n" ); document.write( "x = pi/6, x = 7pi/6 \n" ); document.write( " \n" ); document.write( " |
