Solve the equation 4sin^2 x - 2 = 0 on the interval 0< x <2pi. \n" ); document.write( "-------------- \n" ); document.write( "4sin^2(x) - 2 = 0 \n" ); document.write( "sin^2(x) = 1/2 \n" ); document.write( "sin(x) = +/-sqrt(2)/2 \n" ); document.write( "------ \n" ); document.write( "In the interval 0 < x < 2pi, x = pi/4 or x = (3/4)pi \n" ); document.write( "or x = (5/4)pi or (7/4)pi \n" ); document.write( "========================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=========== \n" ); document.write( " |
