Math Formulas For Complex Numbers
Math Formulas: Complex numbers De nitions: A complex number is written as a+biwhere aand bare real numbers an i, called the imaginary unit, has the property that i2 = 1 The complex numbers z= a+biand z= a biare called complex conjugate of each other Formulas: Equality of complex numbers 1 a+bi= c+di()a= c and b= d Addition of complex numbers 2
Math 101 - Complex numbers and Eulers formula
Math 101 - Calculus II Euler’s relation and complex numbers Complex numbers are numbers that are constructed to solve equations where square roots of negative numbers occur These numbers look like 1+i, 2i, 1−i They are added, subtracted, multiplied and divided with the normal rules of algebra with the additional condition that i2 = −1

Numerele complexe z1 =a1 +b1i şi z2 =a2 +b2i sunt egale , dac ă şi numai dac ă a1 =a2, b1 =b2 Num ărul complex z =a −bi se nume şte num ăr conjugat num ărului z =a +bi , iar num ărul −z =−a −bi se nume şte num ăr opus lui z =a +bi Fie z1=a 1+b 1i şi z2=a 2+b 2i dou ă numere
complex numbers - Iowa State University
One of the more profound notions in math is that if that if we take the exponential of an imaginary angle, exp(jθ) the result is a complex number The interpretation is given by Euler’s formula Every complex number of this form has a magnitude of 1 M = cos2 θ +sin2 θ = 1 re im-0 5 M = 1 0 866 θ θ = 120° = 0 667π ej(120∘) re im 0
