Webcomplex numbers by adding their real and imaginary parts:-(a+bi)+(c+di)= (a+c)+(b+d)i, (a+bi)−(c+di)= (a−c)+(b−d)i. We can multiply complex numbers by expanding the brackets in the usual fashion and using i2 = −1, (a+bi)(c+di)=ac+bci+adi+bdi2 =(ac−bd)+(ad+bc)i, and to divide complex numbers we note firstly that (c+di)(c−di)=c2 +d2 ...

WebWe first write the division as a fraction, then find the complex conjugate of the denominator, and multiply. c + d i a + b i where a ≠ 0 and b ≠ 0 Multiply the numerator and denominator by the complex conjugate of the denominator. ( c + d i) ( a + b i) ⋅ ( a − b i) ( a − b i) = ( c + d i) ( a − b i) ( a + b i) ( a − b i) WebSo that is the magnitude of z minus z1, this first term over here. Let's figure out the magnitude of z minus z2. I'm going to color code it. z minus z2 is equal to the magnitude-- well, z is just this thing up here. Let me just write it out. So it is 1 minus t times z1 plus t times z2, that's z. And from that, we want to subtract z2, so minus z2.

To solve such complex numbers, we have to know the value of i, which we can conclude from the expression, i2 = -1. If we take the square root on both sides, we get, √ i2 = √-1. Or i = √-1. Therefore, the value if ‘ i’ is √-1, which we cannot define, therefore, it is called an imaginary number.
