Algebra.Com's Answer #647303 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Let z = 4(cos 3π/2 + i sin 3π/2) and w = 3(cos π/6 + i sin π/6). Write the rectangular form of z/w. \n" ); document.write( "----------- \n" ); document.write( "z = 4cis(3pi/2), w = 3cis(pi/6) \n" ); document.write( "--- \n" ); document.write( "z/w = (4/3)cis(3pi/2 - pi/6) = (4/3)cis(4pi/3) \n" ); document.write( "z/w = (4/3)*cos(4pi/3) + (4i/3)*sin(4pi/3) \n" ); document.write( "z/w = (4/3)*(-1/2) + (4i/3)*(-sqrt(3)/2) \n" ); document.write( "z/w = -2/3 - i*2sqrt(3)/3 \n" ); document.write( "= (2/3)*(-1 - sqrt(3)i) \n" ); document.write( "--> same answer as Stanbon \n" ); document.write( " |
