Algebra.Com's Answer #388080 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Calculate sqrt(3-3i). Give your answer in a+bi form. In polar form, use the angle 0<(theta)<2pi. \n" ); document.write( "----- \n" ); document.write( "Polar form of 3-3i \n" ); document.write( "r = sqrt(3^2 + 3^2) = 3sqrt(2) \n" ); document.write( "--- \n" ); document.write( "Note that (3,-3) is in the 4th Quadrant \n" ); document.write( "theta = tan^-1(-1) = (7/4)pi \n" ); document.write( "-------- \n" ); document.write( "General Form: \n" ); document.write( "3 - 3i = sqrt(18)(cos[(7/4)pi+2npi) + isin((7/4)pi+2npi)] \n" ); document.write( "-------------------- \n" ); document.write( "sqrt(3-3i) = ? \n" ); document.write( "If n = 0 you get: 18^(1/4)(cos(7/8)pi + isin(7/8)pi) = (18^1/4 , (7/8)pi) \n" ); document.write( "If n = 1 you get: 18^(1/4)(cos(15/8/pi + isin(15/8)pi)= (18^1/4 , (15/8)pi) \n" ); document.write( "--------------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
