WitrynaHere is what is now called the standard form of a complex number: a + bi. It is the real number a plus the complex number , which is equal to bi. 3 + 2 i. a —that is, 3 in the example—is called the real component (or the real part). b (2 in the example) is called the imaginary component (or the imaginary part). WitrynaElementary algebra. The quadratic formula, which is the solution to the quadratic equation where . Here the symbols a, b, and c represent arbitrary numbers, and x is a variable which represents the solution of the equation. Two-dimensional plot (red curve) of the algebraic equation .

WitrynaEigenvector Trick for 2 × 2 Matrices. Let A be a 2 × 2 matrix, and let λ be a (real or complex) eigenvalue. Then. A − λ I 2 = N zw AA O = ⇒ N − w z O isaneigenvectorwitheigenvalue λ , assuming the first row of A − λ I 2 is nonzero. Indeed, since λ is an eigenvalue, we know that A − λ I 2 is not an invertible matrix.
