# Complex numbers have the form a + bi, where a and b are real numbers and i is the square root of −1. All real numbers can be written as complex numbers by setting b = 0. Imaginary numbers have the form bi and can also be written as complex numbers by setting a = 0. Square roots of negative numbers can be simplified using and

som a+bi = (a,b), och adderas och multipliceras enligt f¨oljande formler: (3) (a+bi)+(c+di) = (a+c)+(b+d)i (4) (a+bi)(c+di) = (ac−bd)+(ad+bc)i. Bokst¨averna z och w ¨ar vanliga f ¨or att beteckna komplexa tal. F ¨or ett komplext tal z = a + bi, a,b ∈ R deﬁnieras realdelen av z som Rez = a. Imagin¨ardelen av z ¨ar Imz = b.

In logic and related fields such as mathematics and philosophy, " if and only if " (shortened as " iff ") is a biconditional logical connective between statements, where either both statements are true or both are false. When I was a student, we didn’t have much of a hope in in similar situations, but these days thanks to Algebrator my son is doing wonderfully well in his math classes. He used to face problems in topics such as form of a+bi algebra calculator and trigonometry but all his queries were answered by this one easy to use tool known as Algebrator. 2009-01-06 symmetric bilinear form A symmetric bilinear form is a bilinear form B which is symmetric in the two coordinates ; that is, B ( x , y ) = B ( y , x ) for all vectors x and y .
